We stayed here for 6 nights. Hotel was good, location is not bad - close to metro / train station and bus (flixbus) terminal. convenient and supermarkets are araund. But you can feel unsafe, and streets are dirty and noisy around. 30 min to walk to the beach and 15 min walk to Sagrada familia.
The pool on the roof and very little - 2x4 meters probably, you can not swim there if someone else in the pool.))
But , breakfast - super great and lots of varieties.
Overpriced I would say, for this location we paid lots, 300CAD per night for August stay. Not worth it, better to go close to Catalonia Square, and you need not that pool at all.
