Had a great stay at Laura's apartment. Great location if you are in town for IE Business School.
The internet at the apartment is the fastest internet I've ever seen! Only downside I experienced was how hot it was in the bedroom at night. Without air conditioning (in bedrooms) in July in Madrid, it was really hard to sleep until temperatures cooled down later in the week. We did buy a small fan which we left for future guests.
Overall, great stay and Laura was very accommodating.
