The property was clean and in convenient place. Also I loved the apartment had laundry to use. It helped us a lot. Something they could do better is to keep some tea bags to use. They had coffee machine & tea kettle. I didn't want to buy a whole box of tea bag or coffee for short stay.
Few lights were out, too, which didn't bother me too much since there were a lot of lights to use. One ice cream was left from who knows how many visitors ago in the fridge. I think they can do some good maintenance.
One other thing - the soundproof for the apartment is so bad, you hear so much noise from upstairs. I use ear plugs and sound machine, so it worked fine, but if you are a light sleeper, not the place.
Oh, but the one big plus if you got the right side of the apartment? is that we could see Sagrada Familia from windows. I fully enjoyed the view often throughout the day.
