The room is on forth floor and no elevator. But it is located near subway which is easy to go anywhere u want. We shared one bathroom and it's sometimes busy. But the cleaness is perfect.
The host is comunicative and kind. He has two rooms for guests and he manage well.
Three of us living in one room and we have mattress on the floor for the third person. The mattress is comfortable but it occupy the space for our luggages. But it won't be a problem if you have few luggages.
