We had a nice stay at Yana's apartment. Our room was exactly as the photos. Small, but clean and comfortable, with king-size bed and built-in wardrobe. Windows open to street, not much quiet, but acceptable for us, with good view of some sky-scrapers. Shared bathroom, but it wasn't any problem at all. Nice kitchen, suitable for people who are going to eat out or cook dinners at home (what is wasting of time, as there are many cheap restaurants and bars around).
Yana was a very welcoming host. Although she was on the trip during the first few days, we were still in touch via sms. She also has a friendly cat, called George. Really friendly :)
