I had a wonderful stay at Isidro's apartment!
It is a incredibly soothing place to relax in the middle of bustling Madrid. The apartment is very clean, super equipped and lovingly furnished. The panoramic view of the city from all windows and from the large roof terrace is simply stunning. The location is very central and there are many nice cafes, bars and restaurants in the immediate vicinity.
Isidro is a particularly accommodating and nice host.
I felt very comfortable and can only recommend the apartment!
I will be happy to come back again!
