Both the apartment and Isidre are terrific and you won't feel regret staying there.
The apartment is spacious, with 3 bedrooms and a big kitchen, also tidy and clean. Everything are available in the apartment, with many complimentary items and a lot of travelling guides, including maps, dining and shopping centres. The apartment locates at the centre of city and many sightseeing points are of walking distance. The way to Park Guell is excellent as guided by Isidre, much better than those on the website.
Isidre is sportive and nice, he allowed us to leave at 6pm though the check-out time is noon.
Overall an excellent choice.
