Well, we really liked to stay at Yana's.
Her parents turned to be extremely hearty and hospitable people and took fully into account our wishes concerning the appartment: they provided us with extra electric heater (as the studio is in the basement and heated not well enough), an electric tea-pot and a pan as well.
The studio is indeed very nice and clean, And though the bed is not a real one but rather a folding couch and I would never call the bathroom "spacious" as it is only 1,8sq.m., it is still one of the best appartment we've ever rented in NY in terms of price and quality.
