Mary is really nice and she gives very clear instructions for reaching the place and checking in. She is also very good and fast at answering any question. The room is comfortable but in a very old building where walls and windows are very thin. I didn't sleep much because of various noises and screams coming from the street but this is an ok place if your sleep is hard to disturb. In my case even earplugs (kindly provided by Mary) did not help. The area is really central, connected to metro and buses and with people constantly passing by. At night, I didn't feel very safe being a solo traveller.
