I really liked communication with Laura, she was very kind and helpful. Her friend gave us some travel tips and showed some interesting places on city map.
The apartment was a little bit far from city centre, you have to go 10-15 minutes to metro/bus station and than about 20 minutes to the city centre. But it was not such a problem for us.:) There is also no problem with night buses but they go every 30 minutes approximately. There is very nice supermarket Conad approx. 5 minutes from the apartment, you can find here everything what you need.
The apartment didn't look exactly like on photos but it was good equipped, the only thing I missed (and was mentioned in description) was an iron, but Laura was very willing to bring it.
Some disadvantages: mold in shower and on shower curtain; dysfunctional lightening in living room, missing quilt cover. Don't use a sink in bathroom at the same time while someone is having shower, haha.
Advantages: good wifi connection, safe location, drinkable water in good quality.
Thank you Laura for providing us your apartment.
