The apartment is beautiful and spacious in the center of Barcelona. My son and I each had our own bedroom and bathroom. Living room, kitchen, and dining area are spacious too. AC is nice and strong which is great given the heat wave in Barcelona. The apartment is surprisingly quite too, for being so close to the center. El Raval is an interesting area with a diverse immigrant population, lots of convenient stores, cafe.
Checking in is a bit inconvenient because the key needed to be picked up at the office (which is 20 minutes walk or 10 minutes car ride from the apartment) and we got 3 luggages. That was a surprise to us but the office was able to deliver the key to us after 8 pm. So you plan your schedule accordingly or make it to the office for key pickup.
We enjoyed our stay very much. The office was also able to store our luggages on the day we checked out, and before heading to the airport. Overall a good experience!
