I don't recomend.
There is no central heater, they leave a couple of small heaters on the corridors but you have to be lucky to arrive first and get one before other guests, otherwise you'll fell cold if it is winter.
Hot shower was a problem, I stayed over for 6 days and had to take cold shower for 3 days in a row during the winter. There is a small boiler to heat the water and if the other guests take shower before, you might have to deal with the cold water.
The internet works really badly on the second floor where the majority of rooms are located (rooms 4, 5, 6 and 7).
The place is located on a hill so if you have big or heavy suitcases don't think about it. But it is located close to the subway station and it is also close to some of the attractions of the city.
The light goes off all the time and that is really annoying.
The curtain was broken and instead of fixing it, they gave me a tape to glue it on the ceiling. After check out when I was on my way to the airport, they sent me a message saying that the tape that they gave me had stained the ceiling and I should pay for the painting...
You have to be lucky with the other guests that are sharing the place, otherwise you can have noisy and messy companions.

The hosts are not polite.
