As close as it is to Gran Via it is not too loud or busy. A taxi driver did caution us about about the reputation of the street. It is widely known to be a common area for prostitutes and we did see a few at night. Though it was a bit uncomfortable, the area still seemed pretty safe. The host was very helpful upon check-in with a map and many recommendations. The apartment itself was clean, nicely decorated, and had great amenities. One problem we encountered was that there was not sufficient hot water. We had to take really quick showers before the water turned cold. Tried to inquire with the host but he didn’t reply until the following day (after we checked out).
All in all, it was a pleasant stay.
