The location is perfect if you want to enjoy the gothic quarter :) the communication with the host was helpful and friendly. BUT
1. The apartment is noisy 24h round, for morning to evening there is construction noise, at night till morning the clubs and bars. If you wish for a some peace and good night sleep - this is not the place for you.
2. Note that the apartment is on the second floor with no elevator. For a family with 4 suitcases it was a hassle.
3. The apartment is not in a good condition - the walls are dirty, the curtains are dirty and torn and there is a bad smell of smoking.
I think at best this place could work for young people looking for a place in the heart for the city. Would not recommend for families.
I think the place has potential but the owner would need to to a serious makeover and renovations.
Good luck
