First and foremost, the apartment is absolutely beautiful. It's much bigger than we expected and decorated beautifully. We wouldn't hesitate to stay here again.
The location is absolutely perfect for getting around Barcelona. We walked everywhere.
A couple things worth noting:
-The apartment is rather large and the internet does not reach the back bedroom. Even though they have another router in the back, it did not work and the host was not able to fix it.
-There is a large projector TV in the living room which we were very excited to use, but this too didn't work and the host could not fix it. Kind of a bummer after a long day of sightseeing and wanting to unwind.
-The house was mostly clean except the bathrooms could have used an extra pass. There was a bunch of hair around the sinks and under soap dishes. They also left a dirty rag in the shower.
-The AC in the back bedroom was never as good as the first day we were there. Might have been our fault but it got warm in the back quite quickly as Barcelona was quite humid.
Again...this space is amazing, and our friends who had booked a suite at a local hotel came in and their mouths dropped with envy. Most of the more expensive suites in town are quite small, and this is very, very large. It was only my wife and I staying here, but it would have accommodated 2 couples very easily.
