Olga's place is nice and cozy - well equipped kitchen in which you can cook your own meals, little living room to chill, dining room table. The location is nice - good, quiet neighbourhood with good public transportations. Bus and subway just a few minutes walk away. There is a supermarket 7min away which is also very convenient.
The walls and ceiling is very thin, so we could hear foot steps, conversations, phone ringing, TV etc. which we didn't like as we came for vacation and it felt a bit not private. So if you want to sleep late -don't forget your earplugs!
