The apartment has a great location. it is located in the distance from the touristic hell, but perfectly connected by the public transportation. A bus D20 stops just nearby and can be used to reach the beach. There are 2 or 3 metro station within a couple of minutes of walk. Please note, that if you need a lift to go down to the metro, then you should walk to another entrance which is located a bit further down the av. Parallel. Also, a big plus is that a door of the building fronts to a smaller and much quieter street than av. Parallel.
It can be a bit noisy at nights, but we didn't have it over the comfortable level. We were staying with two kids and it was ok.
Apartments are very clean and well-equipped. A block of bedrooms is separated by a door from the rest of the flat. No need to keep it too quite if somebody is sleeping, while the rest of guest are having fun in the living room.
There is a good TV and pretty fast and stable Wifi. I worked remotely and it was pretty critical for me to have a good connection.
The place is managed by an apartment network and you have to grab keys in an office which is located on a road from the El Prat airport. We were arriving very late, so I don't know if it was the case for day time arrivals, but I think it is a plus, because you don't have to pay an extra fee for the late check in.
And last but not least, Jacques is very helpful and responsive. He was super kind and flexible about the late checkout, which was very important for us to keep an usual day sleep for our kids.
