My wife and I enjoyed our time in Madrid.
About the apartment:
-The apartment location is just perfect, overall it was quiet (so we could get enough rest during the night), the wi-fi was OKish (sometimes there were some freezing/stuttering), all utilities worked just fine.
- The bed is comfy, we had no back pain or similar issues.
- There is an elevator to reach the apartment (4th floor).
- The place really needs a full renovation.
About communication with host:
- Gonzalo was very responsive on WhatsApp or AirBnb messaging, he helped us with useful information before check-in, and also before check-out.
- We never met Gonzalo in person, but with Rosa (to handover the apartment and the keys).
