This place is in a fantastic location and was very clean.
However, it is in an older building so the sound-proofing is fairly poor (e.g. I could hear the neighbour whenever they coughed, and there are flamenco dancers and live music next door). There was also a bird or some other sort of animal in the ceiling making noises throughout the night, which was annoying.
Another minor issue was that one of the shower stalls was very small and the water temperature was highly variable, but the other shower stall was fine.
