Lima

Loved Miraflores in Lima - has a lot of stylish cafes and restaurants with good food, coworkings, parks. Barranco has some amazing nightclubs. Although Lima is more expensive than other parts of Peru

Well, I was about to write a review but the poster from 2 days ago pretty much said everything I wanted. I will add that the cafes in Barranco are usually nicer to work from than Miraflores. There are some nice ones in San Isidro as well.

Hot tip: keep a look out for signs that say "menú", from these hole-in-the-wall restaurants you can get a full meal (drink, appetizer/soup, entre) for 10-20 soles depending what you get and where. They are everywhere, but I didn't notice them until the end of the trip. Locals eat at these places, and the food is pretty good (although be prepared for lots and lots of rice with fries)!

I stayed in Lima / Barranco district for 1 month, and loved it. For context, I am a 28 year old male from USA, I work remotely as a software developer. I'm also speaking mostly about Barranco and Miraflores, as I diddn't go outside of those districts much.

Barranco is full of many great cafes and restaurants, and its very walkable. There are nice paths & parks along the ocean where you can get a great view as you walk. I would recommend staying here, and taking an uber if you want to go anywhere else, Uber is very cheap ($3 USD for 10-15 min ride) and it works great in Lima.
Miraflores is also great, but it is alot more modern, bigger district, larger buildings, and feels a bit less "cozy".

English is not common, even in the touristy restaurants and shops, it seems like 80% of people dont speak any english. You will need to learn some basic spanish, or use google translate alot.

The only downside I can think of is the traffic. It's very hectic, hard to cross the streets on foot, and alot of honking and noise. But overall it's a fun city, and I will be back

One of the most horrendous cities I've ever been to. Too much traffic, ugly architecture and even the food is very much hit and miss. Oh and housing is not that cheap. People can range from very friendly to very much not caring but on average, they're neither unfriendly nor easy to connect with, even if you speak good Spanish. More than anything, from someone used to the lively vibe in Colombia or Mexico, the place is as lively as a cemetery. No music, not even a peep at night... There's a reason why most people skip it and head straight South even though they land there. It's simply a boring and ugly city. No one in their sane mind would choose to live there.

I spent a couple months here and loved it. I studied spanish in a school called Peruwayna in the heart of Miraflores. The school was great and this was a great way to meet people. I went to a couple hostels to meet up with some friends, and met a lot of really cool people that way. Loki is a really cool place in Miraflores to hang out and stay if you're doing the hostel thing, and like to drink. I had a very nice private airbnb in miraflores for less than $30 a day. I also stayed in Barranco for $32 a day in a very elegant condo with 2 beds and 2 baths which was about a half mile away from the action. Virtually everyone I met was kind and welcoming and really liked that I spoke the language. Barranco is a really beautiful place to watch the sunset, and the nightlife is really cool. Uber is cheap and reliable. I avoided regular cabs because I didn't want to negotiate and end up with a gringo price. If you're going to the airport, get a private taxi. I say this because I almost missed my flight home after two Ubers showed up and rejected me once they found out I wanted to go the airport. Luckily, the third was agreeable.

You'll want to know at least some basic spanish to get around. If you have a conversational level or are in the process of learning, you'll get a lot more out of the experience because not many people speak english. The food is delicious and unlike the food anywhere else, though most of the local cuisine is a bit heavy and unhealthy. You can easily eat for half the price of major American city, and probably a third of that if we're talking NY,LA, or San fran. Ask about menus. Those are lunch specials for $3-4 that include 3 courses and a drink. They're usually really good too. The happy hours are usually 2 for 1, meaning 2 drinks for the price of 1, which is better than most US happy hours. Especially considering the original drink you're buying is a lot cheaper in the first place. Don't buy souvenirs in miraflores! You can get that stuff much much cheaper in the centro de Lima just don't linger there after dark, because it gets very sketchy.

I never had any security problems or felt unsafe. I also live in Baltimore, one of the most dangerous cities in the US, and I felt much safer in Lima. I know women need to be much more carful, because there is an epidemic of sexual assault in Lima, especially on public transit. The visiting women that I met never complained to me about any problems, but I have heard quite a few stories from local women about being groped and/or catcalled. I was warned many times to be careful with my cellphone in public. If you're talking on your cell in public, at least be aware of your surroundings because there are many people who specialize in grabbing your cell from your hand quickly and running off. Though technically illegal, weed is easy to find and cheap, and you can pretty much smoke in the street without worrying about cops bothering you, if that's your thing.
