Moscow

I am from Moscow but grew up abroad. It's a lovely city, it's hard to find another city that matches the amount of cultural activities there are. Every day there are at least 2 festivals, 3 major concerts and tons of shows in theaters. The best season is winter and summer. The amount of decorations in the winter is incomparable (to London for example)! Snow adds magic to the city and if you are worried about the cold, there are plenty of shops with high quality winter clothes at decent prices. The city is very big, it will take ages to get somewhere and back, so only about 2 activities a day unless you live close.

Moscow is a great city, especially for young and adult people. Many business here and a lot of fun. Cheap taxi. Very clean city. Online delivery 24-hours for everything! Great and cheap subway (metro). Many cultural experience, good and different food. Fast Internet and free wifi in most of public places.

The best city I have ever been. But you will need google translate if want to communicate with most people.

Lived in Moscow for a year in 2019. I worked in the mornings and late evenings working in multiple locations across the city (mainly centre) and travelled via metro/walked. Never had safety concerns. M29yo

You can have MGTS landline internet 500mbps for $10/mo. Only swiss products in groceries, no EU due to current sanctions. Really cheap life, if you are rich i'd recommend AzbukaVkusa groceries. A lot of expensive restaurants.

I'm from Moscow though do not live there at the moment.
Actually it's a good city to live in if you enjoy big cities. Lots of activities (including lots of free ones), huge parks, very walkable, great public transportation, groceries are cheap, people are nice but seem cold because of their mentality. You can go to Moscow region by commuter train to enjoy the countryside or swim. Safety is underrated. Moscow is very safe, it's totally ok to walk at night, I had nothing stolen in 7 years of my living there as a student. Much safer than in Southern Europe I would say. Wifi speeds are skyrocketing and you can pay with card nearly everywhere. Yandex is a leading taxi hailing app (that bought Uber Russia).
On the other hand it's a giant city with 14 millions inhabitants, 4 airports (please don't use ZIA), 9 railway stations, so it can be quite a mess. No good food. Air quality is very low, returning from any other place I could literally smell the air. And winters (Nov - Mar) are grey and boring, snow is melting and freezing again, everything around is filthy, very depressing, that's why so many Russians who work remotely leave the country and spend winter somewhere in Southern Asia. Airbnbs are super expensive compared to local long-term rent boards like Avito. There you can also find options for several months but if you don't speak Russian you would need a local friend. The rent is expensive compared to St Petersburg and other Russian cities. Older people don't speak English.

Moscow is incredible for digital nomads. Lots of coworkings, including WeWork, plenty of bars, and restaurants. Nightlife is awesome - from usual nightclubs to techno spots etc. It is much more safe to there than in other European capitals (London, Berlin, Paris). You only need to be careful with illegal things like cannabis and other drugs because of zero tolerance. People are great, and girls especially.
People look unfriendly because they are not smiling to everyone, but it is just because of mentality.

Privet! I think Moscow is much cheaper then on scores and internet is much faster and if you spend summer time there then it is an amazing place!
