My daughter and I stayed in Juan Carlos's flat for 4 days. It is the most spacious and most comfortable Air BnB we've ever stayed in while traveling Europe. The bathroom is clean and had a supply of toiletries if you forgot any. There were so many wall outlets available for charging (just don't forget your converter).
Pros:
-close to metro
-quiet
-clean
-spacious
A few things to consider:
-no a/c but we were provided with a fan which we had to move constantly depending on which room we were at, but it wasn't that bad.
- the flat is on the second floor. No lift and winding stairs.
Overall, this is the best Air BnB we've stayed in while vacationing in Europe. We would definitely stay here again. It is the most homey. Wish all the BnBs we stayed in in Europe were like this one.
