My 3 girlfriends and I traveled to Spain and Portugal for a girl's trip. This by far was our favorite accommodation. The apartment was squeaky clean, nicely decorated, came with a full kitchen, washer/dryer and 2 air conditioners and the beds were comfy! When we arrived the host's son informed us that the modem wasn't working and so he went out to get us a new one right away. He left and came back within an hour or so, set up the modem and made sure we had wifi. An added bonus is that this place is literally around the corner from the Sagrada Familia, the metro, taxi lines and various restaurants and coffee shops.
Overall, we had a very pleasant stay here, and would highly recommend this place to anyone.
