We highly recommend this apartment!
We were 2 people and spent a week in Hanzel and Titi’s apartment. It is very easy to access from the airport, It's direct and only 30 min ride with the aerobus.
Titi was very friendly and gave us a warm welcome, she told us about the main things to know about the apartment and a few tips about the city.

The apartment is in a really great area. There are tons of grocery stores in the location, it’s a 10 min walking distance to the main streets like Passeig de Gracia or Rambla Catalunya with good bars, restaurants and shops. It’s also a 5min walk from the Metro station Universitat.

All the common areas of the flat, the entrance door, the stairs and the lift were in very good conditions.
The apartment itself was charming and luminous as shown on the pictures. The atmosphere and the furniture were really comfy and cosy. The kitchen was very well equipped with brand-new utensils. The bathroom is very nice with a big shower, and it is well-equipped with lots of towels. We didn’t use the bedroom as we felt that it was not really welcoming (no window). We used the pull-out bed of the living room instead, which is awesome and comfy. The authentic floor and the tasteful decoration were really pleasant. The AC was a big plus as it was super warm when we were there.
The area is calm. The only bad point to say was that there were some constructions happening in the building next to the apartment during our stay… It was unfortunate but not a big deal as they were usually starting around 11am.

Cheers!
