We just spent five nights at Irina's place! The apartment was even nicer than in the photos. It was bright and had these huge, beautiful windows. It is also conveniently located around various grocery stores and just two blocks (quick 5 min walk) from 6th line metro station. You'll also find famous local pizza place just around the corner which was a nice bonus for us as foodies. Definitely a good value deal!
However, be aware that the apartment is located on the 3rd floor and the stairs are rather steep if you are coming with huge luggage.
