The location is excellent, a few minutes from the metro and a quick walking distance to the Gothic Quarter. Plenty of shops and places to eat nearby. It was rather quiet at night and the bed is large and comfortable.
On the downside, the communication with the host was slow (no response for days prior to my arrival and slow communication when I was there). I felt that more transparency would be good, for example mentioning that there's a dog at the apartment (not an issue for me, but perhaps for other guests) and that there are occasional issues with hot water (it turned cold in the middle of the shower once).
All in all, an OK experience.
