The best part: excellent air conditioning, which was really important given how hot and humid it was in Barcelona. Comfortable beds. Good hot water and water pressure. Lots of space; beautiful place. The bad part (and within control of the host): safe needed new batteries, which I informed the host about and the response was (after more than an hour, which was the promised response time) "I'll let maintenance know." Since I couldn't lock up my passports, I didn't report other issues because I didn't want anybody else there without my passports locked up): one bathroom doorknob fell off inside the bathroom; the apartment door needed to be slammed to get it to shut (common in the building), the drapes let in a lot of light, the refrigerator didn't get cold enough to safely store food. The light switch didn't work properly in one bathroom; the control of water temperature in one shower was poor (with scald potential). The bad (not within control of the host): noise transmission through the walls and ceiling. This alone made it impossible to get restful sleep. The host was informed once but didn't respond to the issue. The elevator didn't work for several of our days there (we were on the 4th floor, although listed as 3rd floor in the numbering style Spain uses). Had we had problems with stairs, we would have had to leave.
