It's a fantastic location - 5 minutes east of Plaça d'Espanya, a 5 minute walk into El Raval, and super close to Montjuïc. Lots of amenities nearby, and quick links all over town with Poble Sec and Sant Antoni Metro stations very near. The flat itself was well presented, clean, and clearly well looked after. Comfortable sofas, and plenty of seating for 9 people. There is also a folder full of suggestions for your stay. Special mention for the bamboo pillows, which are probably the most comfortable I've slept on.
Mai was an excellent host, accommodating a couple of guest changes before, meeting us as we arrived, and allowing us an extra set of keys. She also allowed a flexible check-out time, as part of our group had a later flight. Throughout, communication was quick and clear. She could not have been more helpful.
