Great location and very walkable. 25 minute walk north to Park Güell (steep hills), 25 minutes east to LA Sagrada Família, 20 minute walk south to Casa Batlló. Good neighborhood with lots of food options.
The apartment was very spacious with comfortable beds, bedding, and pillows. One room is enormous with a sitting area and balcony. In our group we gave that room to grandma and grandpa. But 2 of the rooms fit nothing but the bed. Worked okay for us with kids. The additional room only has a curtain (no door). The kitchen is TINY!! The size of a postage stamp. The only "counter" space to prep any food is on top of the electric cooktop. It meant for us we didn't cook in the space, but it was still nice to have a fridge for use. Good cold a/c but need to leave your bedroom doors/curtain open for it to cool down the rooms. Washer/dryer combo was very convenient for doing laundry.
We had a few maintenance issues during our stay. TV wouldn't load any channels, bed frame was broken (bottom 2 legs were missing so the bed tipped over), shower leaked, lights flickered all night when turned off, and then the last 2 nights water leaked from the floor above in one room onto the bed making all bedding wet. The host team were quick to send out technicians (the next day), but one room was basically unusable for 3 nights of a 5 night stay and we had our stay interrupted with maintenance staff on two days. They were very friendly and fixed all issues except the water leaking again the next night. It meant 2 of my kids were displaced to a couch (not a couch bed) and the floor. I asked for a discount and was offered 5% for the 2 nights (approximately $25). Not sure how that makes up for one completely unusable room, but okay... I did not feel that response was reasonable.
Overall we really liked the place and hopefully they will fix the issues with the water for future guests. Overall I would recommend the place if cooking at home isn't a priority for you.
