The best thing about 315 Euro is the location and included parking.
Otherwise we felt our studio to be somewhat dreary space. The sleeping area was separated from the kitchen/living area by the bathroom. With the door to the unit right at the bed, noise from the hallway, only small window in the bedroom. The bedoom is so small, no room for suitcases so had to keep them in the living area. The living room looked over the car park, trash and recycle bins. There is a restaurant next door, if you have the window open you are subjected to heavy garlic and curry aromas at times.
A caution when reading reviews and the description, we did not feel our unit to be stunning, but rather quite basic. As well, if you are reliant on wifi, it was poor in our unit, either not accessible or extremely slow. Could only access it from the living area, not the sleeping area. Also the building we were in did not have an elevator.
