The apartment was exceptionally clean, it is as it shows in all the photos. We stayed as a family of four so it was nice to each have our own room and extra bathroom. We were greeted when we arrived by the hosts and who had a nice big bowl of fresh fruits for us and have us some suggestions on restaurant and transportation. The metro (both bus and subway) are very close and can get you to all tourist places quick. The Sants neighbourhood is not touristy but very lively and lots of restaurants and shops. The one bedroom that faces the alley can be a bit noisy as the garbage trucks come in the middle of the night to pick up garbage and it seems to be a walkway for locals.
The apartment air conditioning was excellent in all rooms which was needed our first few days as it was very hot. The Wi-Fi was also good. We enjoyed the balconies overlooking the local area and right next to the market which was very handy.
The Hop on Hop Off stop in Sants is very close so you can catch up up the road. We also took a train to Sitges right from the Sants Train Station and a bus right to Barcelona beach. You can walk to the Espanya area within 20 minutes and see the Montjuic Fountains. We also enjoyed eating up top in the old bull areana.
Overall, an excellent apartment if you want to be in typical Barcelona neighbourhood, close to metro and have the convenience of big space and amenities for a family or another couple.
