Great location and functional apartment. You can easily walk to many of the sights in Barcelona or access public transport if needed to go farther away. Julia was great with communication and the check in, everything went smoothly. There is a nice overview of her recommendations for restaurants and activities in Barcelona. The appartement is quite large compared to a hotel room, it can easily accomodate a group of 4 with the master bedroom and sofa bed, and has room enough for everyone to relax.
The apartment is located on a street which can be busy at times which leads to some noise in the apartment. The balcony doors do a great job at blocking the sound but bot everything when it is busy. When other people use the stairs or elevator, this can also lead to noise. The noise did not bother us but personally, but be aware. The curtains in the master bedroom are also not very light blocking, it did bot bother us personally.
Overall if you're looking for a location to be able to easily walk a lot in Barcelona, this is a great choice.
