Communication with Carlos was excellent. We really appreciated that we were able to drop-off our luggage earlier in the day (basically after the previous guests left, and before the cleaner did her job) as we arrived in Barcelona very early and check-in wasn't until 2pm.

The apartment is great and just as in the pictures. Lots of space for 6 people and we had a great lunch there with lots of tasty food from a nearby market hall.

The area overall is very convenient, Sagrada Familia is just a few minutes walk away and most of the other touristy areas are all in walkable distance - or alternatively a few tube stops away (if walking isn't your thing).
