We had an awesome stay at the apartment. Everyone is so welcoming and the apartment is one of the few that actually looks modern, which is rare in Barcelona.
Everyone is very quit in the apartment and you are allowed to use the kitchen with oven/stove and microwave in it.
The Building has an elevator, which not all of them have in Barcelona and a well sorted supermarket next to it.
To get to the city center is only a few minutes Bus ride or 20 minutes walk, so even if it's not super central, it's so easy to get anywhere, as it connects directly to the busses and metro.
110% recommended, the best deal we could find in Barcelona!
