A nice apartment in an excellent location. Easy walking distance to restaurants, shopping and tourist sights. The apartment itself is one of several rentals run by the same folks in Barcelona. I found them to be easy to communicate with and responsive. They even provided after hours entry instructions in case I arrived when there was nobody on site.
The apartment has three bedrooms, one with a legitimate bunk bed, which I believe would be really nice if children were staying.
An additional touch - the apartment comes stocked with a variety of beverages, much like a large mini bar - which can be used and added to the room tab.
