Paola was very nice and fast to reply, and ensured that checking in was smooth. The apartment itself is very basic- there are small rooms and beds with shelves in them- nothing extra. There is also no Tv or air conditioner. It was especially noticeable in the rooms with no windows to the outside. We also couldn't fall asleep up until 1-2 am because of the noise from the streets. There were two small but clean bathrooms and a big kitchen area where you could hang out. The kitchen had all the necessary stuff to cook.
Even though the apartment was in a nice area near the Montjuic, walking to the Gothic quarter was a bit unsafe because of some strip joints on the way and lots of drunk people on the street. Luckily, everybody were friendly, and we could figure out another route to the centre later. I would recommend this place for a bigger crowd 5-6 and preferable young people who come home to sleep.
