We had 6 nights in this apartment. It was spacious, clean, full kitchen (though we did not cook), hot shower with excellent pressure from the rain head. Bed was comfortable.
Location was excellent. Only a 5-10 min walk to Sagrada Familia. Bus stops across the road, metro 5 minutes away. Restaurants very close by. Easy check in - we were given a map and the main sites were shown to us including which metro lines etc to use. WIFI decent, however only works in the living room/kitchen, not in the bedroom. Lovely views from the bedroom over the old hospital. Some road noise, though that's to be expected in the city. We would definitely stay again.
