This was a really good stay. The location is second to none... you can access basically all of the major attractions, restaurants and shopping in less than a 20 minute walk.
The apartment is exactly as the pictures show. The terrace is huge... and you really feel like you own Barcelona. The layout of the apartment is convenient and efficient. Perfect for a family of 2 adults and 2 kids.
Although the apartment was perfectly clean, it didn't feel "sparkling" - We believe it needs a very deep clean to ensure freshness and to bring out that "special" feeling that the terrace evoques.
Please bear this in mind: this apartment is located in the rooftop of an office building. This is great in terms of not having any neighbours to annoy in the evenings, but on the downside the rooftop is is shared with the elevator machinery which makes loud clunking noises that feel a bit weird inside the apartment, from roughly 7 AM until 7 PM. The noise did prevent us sleeping in but hey... it depends how much of a light sleeper you are.
Communication was good and clear. Check-in is only available at their office which is a 15 minute walk from the apartment, so do contemplate that in your planning.
All and all, a really good stay. Thanks!
