Very very (!) little luminosity in the flat. The pictures do not reflect the reality at all. I call it "a tinder-like advertisement". Be aware that you will have to turn on the light at any time of the day without exception. Little water pressure in the kitchen, non functioning air extractor above the stove. I stoped cocking after a couple of days as it made me nuts. No window to the outside in the sleeping room: it is very hot (in the summer) and there is little air.
The bed and sofa are good enough. The TV and the rest of the equipment work well. Well located flat in a likable and safe area. The metro station "parallel" is 5 minutes away by feet and connects you to the rest of the city very easily. The building is quiet. The landlord is lovely, polite and will give you use-full information about the area and Barcelona. The flat is clean.
The flat is good enough if you plan to be outside most of the time (tourist) and you are looking for a place to sleep.
If you are looking for a place to live and cock it might this flat might disappoint you.
