We generally enjoyed our stay at Maria Luisa's apartment. Definite pros include the location near Joan Miro park, the wonderful terrace, the kitchen and laundry room, and the separate air-conditioning for each room.
The minor downsides include the lack of windows in 2 of the bedrooms, and the beds being shorter than what we are used to, so our feet were hanging off the end. The beds could have been more comfortable.
When we arrived Maria Luisa greeted us warmly and began to provide us with lots of helpful information, including maps and lists of restaurants and things to do. She only speaks Spanish and so there was a friend to translate, but Maria Luisa's rapid delivery didn't allow the translator to keep up. We did get the gist of what she was conveying though.
We enjoyed our stay all in all.
