The worst thing I can possibly say about this place is that I'm peeved that I only get 500 words to rave about Alfonso and his penthouse.

The situation:
I was traveling with a group of 4 other friends and we were all arriving at different times, with different priorities, and different preferences. Alfonso's place stood out to me in particular because of it's size, location, amazing view, AC (summers in Europe can be brutal without a good unit!), and Super-Host status.

What happened:
Since there were 5 of us coming in at different times, it was a nightmare (sorry Alfonso!) to arrange who would get the keys and when. A portion of the group was doing a paid-city tour when arriving and were unsure what time they would be available to meet up Alfonso for the keys while the other portion of the group was getting in much later.
Alfonso was super helpful, responsive, and flexible with our schedules and we were able to get in without a hitch!

The place:
The pictures do not do this place justice. The place is absolutely spotless and the balcony view is phenomenal. If you ever want to know what it's like to wkae up with the perfect view of Madrid each morning and evening, book this place; it's absolutely magical.
Additionally with two bathrooms fully equipped with a shower (great water pressure) and toilets (large and great flush power!), we all were able to live extremely comfortably.
Additionally each room had clean sheets, towels, and there was even a washing machine with provided detergent that we made great use of for our trip!

All-in-all, if this place is available for Madrid trip...BOOK IT; you'd be a fool not to :)
