Juan's space was fabulous and quiet. If you're sensitive to the heat or the weather is extremely hot, consider another place because there is only standing AC units instead of central air. The temperature during our stay was 90⁰ F, but the night cooled off the space a bit and even my Scottish boyfriend was able to manage fine. We didn't spend a lot of time in the house, but our nights were quiet and the area was very safe. Plenty of wonderful Restaurants within walking distance and the train/bus/metro is very close.
I recommend just leaving your suitcase at the station if you arrive before check in. We arrived early in the morning and our instructions mentioned we could check our bags for €5 in front of the apartment, but no one was at the desk. When we called, the host and co-host didn't seem to remember that instruction or maybe misunderstood and we accidentally stressed them out as they thought they needed to rush and help us get into the apartment hours early. I felt bad about it and think it would have been easier for everyone to just leave our bags in storage at the station.
Aside from that little moment, everything was smooth and we did appreciate them helping us get in earlier. The apartment is absolutely beautiful with amazing views of the water and boardwalk area.
