Nice place, well sized rooms for the most part. Four of us stayed and it didn't feel crowded apart from the bathroom which is tiny, but does the job!
Location is decent, away from the crowds but v near to metros and the Sagrada Familia. There is also a supermarket right next door to the apartment block which was super handy.
Had all the amenities you would need for your stay such as a dishwasher, washing machine, hair dryer, lots of wardrobe space etc. There were a couple small drawbacks - air con wasn't quite strong enough to keep the back end of the flat cool, although fans were provided to help. And the lift in the apartment block was very old and could only take two people at a time when we were there due to this.
Host was great at check in and gave us good local recommendations for things to do and places to eat.
Beds were a little hard for my liking but that is personal preference - other guests with me slept just fine!
Overall had a good stay, good value for money.
