Great stay in Barcelona! All and all I would certainly recommend this place.
-:) Pros:
1. It was great to have a beautiful sunny terrace to spend time and relax while lounging before a late dinner. Very relaxing spot to sit with friends or have some wine. If you needed a break to relax this was a great area to be in.
2. Very quaint neighborhood that felt like you were living in Barcelona. Great cafes around, supermarket for shopping. Favorite cafe: Taranna.
3. Carrer de Blai is nearby and has a TON of restaurants and bars for pinchos! We walked around and stopped in as many as we could.
4. The apartment was spacious with a big living area and kitchen. There was a (small) elevator so we didn't have to lug suitcases.
5. Nice to have your own bedroom spaces.
6. Good size clean bathroom.
7. Mires was very kind. (Most of the time) quick to respond.
8. Mires did not have a guest the day we were leaving, and allowed us to leave our bags until 5:00pm!
9. Close to the subway.
-Not cons, but things to consider:
1. Again Mires was very sweet she was very responsive, except the most important time, on check-in day. *It was a bank holiday when we checked in and Mires was on vacation, understandable* On check in day she was missing we were waiting outside the apartment for 1-2 hours. *It may have been an issue with AirBNB because we were not given the apartment number.* But Mires failed to tell us to just buzz in for the cleaning woman. I finally went back to old review and found the apt # and the cleaning woman let us in. She almost left, but I asked for a tour. Once I did she was very sweet and helpful. Mires was VERY apologetic as she was on vacation. And let us STAY LATE :) on check out day.
2. The beds are a bit stiff; the bedrooms are simple but get the job done. The furniture is more bare bones then the current picture shows, but again gets the job done.
3. A bit of a walk to the bigger tourist areas, but Barcelona is generally spread out so it depends what you want. Plus, the metro is close.

Long story short, I would recommend this place. Relaxing and simple, no fluff and great neighborhood area.
