We enjoyed our month-long stay and like others before us, loved the apartment's location and proximity to metro stations, grocery stores, and attractions within walking distance. Lots of wonderful natural light throughout the apartment. Great bed, blinds that really block the light for a good sleep, nice shower. Everything was clean and worked well. Nuria was very responsive when needed.
Outside of the host's control, there was one very loud person who seemed mentally unwell causing quite a bit of disturbance regularly in the adjacent square while we were there. We imagine that's not a regular experience here, but it was something that affected our home environment during the month. Other than that, we very much liked staying in Nuria's apartment and being in Lavapiés!
