Odessa

It's a nice city on the whole. In summertime you get a lot of tourists from Ukraine, and also other countries. The cost of living is reasonable, a standard meal in a decent restaurant will cost you about 200uah. Internet is fast and good quality, currently you can get a 4g data sim with unlimited data from Kievstar for 100uah for a month. Accommodation can be hard to come by and expensive during the summer months. It's largely safe, but Odessa is historically a criminal city, but most of that crime is not at street level. There have been increasing numbers of reports of foreigners having their drink drugged by "ladies of the night". Common sense prevails and you should not walk around quiet areas of the city at ngiht whilst inebriated.

Charming old town, with a italian/french architecture, the rest is Soviet style + it has a multiethnic diverse community inside it. Cheap cafes + restaurants/pubs and so on. The narrow streets + the main pedestrian side are a beauty in disguise so you people should take the chance in seeing it.

There are more than 5 nice specialty cafes with wifi and good vibe where Aeropress coffee is less than US$2. Decent hostels, and milder weather than in Kiev.
