I was traveling solo for a week and was looking for a clean room with convenient access mass transit. Monica's room fit the bill perfectly and the actual room was very consistent with the description. I especially appreciated access to the washer, as Barcelona was very hot during my time.
As other reviewers have noted below, the building doesn't have an elevator (they're currently working on it) and the room does not have an A/C (quite common for European apartments from what I understand). It was not an issue for me, but may perhaps be for those who have mobility/heat-related health concerns.
Monica was a very responsive host and I had no issues. She's very friendly and gregarious (she has led quite an interesting life) and more than happy to share her thoughts.
