The apartment itself is accurately described by the photos and the listing as well as having a fully equipped kitchen, big comfortable bed, and fast reliable Wifi. Conveniently located within walking distance to most of BCNs attractions and very short distance to multiple metro/bus stops; ideal base for exploring the city. Denis & Christina also communicated well up through the check-in process to answer any questions I had.
However, as previous guests noted, the park outside is - extremely - noisy from 5pm until after midnight. I mention this in case you need to work from the apartment during those times (or if you're a light sleeper), it will likely present a problem. There were also a lot of bugs in the apartment/building and an issue with the door's main lock jamming that kept me out of the apartment for 1 night. Good value for short-term stays but it comes with it's tradeoffs
