We stayed in room 6, and the only negative was that the window faced the alley and not the brighter, more beautiful street.
Other than that, sound traveled but honestly the noise of other guests wasn’t too much a bother, and it was actually pleasant to have contact with other people at times.
The location is great. Five minute walk to the metro, fifteen minutes to principe real, and you could even walk downtown if you really wanted.
Hosts were communicative and accommodating.
