We just spent a week in Mariola's apartment and it was outstanding in every respect. The apartment is clean, safe, well equipped, nicely furnished, easy to find, and perfectly located for exploring Madrid (which is a beautiful city). Mariola is truly a Superhost. His communication is excellent and he goes out of his way to be sure you have everything you need. I would definitely stay there again, and would highly recommend it to my friends, family, and anyone looking for a great place to stay in Madrid.
