We stayed in the apartment 2529. Great location near to the Park Güell, just 1-2 minutes from the Metro station Lesseps (only few minutes to the centrum Placa Catalunya). There is a bakery in the next building, but also just 200-300 meters next to the Metro entrance a bigger one, where one can have breakfast.
The apartment itself is conveniently equipped: full kitchen, wash machine/tumbler, with 2 bathrooms. Enough towels.
The only issue we had was with the water: there is not enough water to shower. Also, the lavabo in the master bathroom was clogged. We tried some make-shift pumping, sometimes it worked sometime it didn't work. So that we couldn't use the second bathroom fully. With us with 5 people (2 adults, 3 kids) it was really difficult to get through with 1 bath and water problems. But reporting this, Airbnb/Office reacted and answered immediately, unfortunately it was through the Easter holidays so it couldn't be fixed.
We could recommend this apartment for 3-4 people.
