Best: location!!! Just opposite to Guell Palace，which open to public on 2012 and just a step away from the most famous La Rambla street. In the middle between the harbor and Catalunya place.
Good: shower in the main bath room flows well with high volume of warm water. Downstairs you can see a police station which makes me feel safe, also quiet at night.
Not so satisfying: the only double bed is put together with 2 individual bed. Not continent for couples...
About check-in: very continent. It has reception on floor EE all day, so don’t worry if you arrive earlier or late(the reception is a very friendly girl). Also, the department lock is an electronic one, no worry of losing the key. i guess the whole building may have 5 to 6 separate department to rent on Airbnb.
