Hazael was really easy to communicate with and very accomodating with my changing schedule. The apartment is ideally located in the Gothic Quarter / Born area. You can find plenty of good restaurants, bars and local craft/art/design within a few hundred meters.
Beach is within walking distance and so are lots of touristic attractions. Otherwise, there's a metro station 2 minutes away.
The apartment in itself was great. You have private room, bathroom and dining area at your disposal. And even though I was sharing the apartment with the hosts, it really felt like I had the whole place to myself.
The streets are a bit noisy at night, but I always carry ear plugs and I was able to sleep properly.
Couldn't recommend this place more.
Thanks to both of you.
