Ideally located for arriving in Barcelona and moving around on the metro - walking distance to Sants station and the National Art Museum of Catalonia, close to line 1 and line 3 stations.
Probably better for a younger single traveller - the room has all the basics you need, the bathroom and kitchen are ok, and there's a supermarket on the same street.
Communicating with Marly was very smooth (English or Spanish) and she made checking in and out easy. Definitely a good choice if you are staying a couple of days or moving to a different hotel like I did (for a sports tournament in the city).
