This was our first time using Airbnb, and we couldn't of asked for a better first experience. Our host Vanessa was there waiting for us and not only did she show us everything about the apartment, she was also like a personal concierge ready with maps and many recommendations of what to do and where to go. Vanessa also said that we could contact her at any point during our stay if we needed anything, but we didn't as all we needed was already applied.
The apartment itself was furnished to a high modern standard and immaculately clean. It is also in an amazing location within walking distance of almost anything in Madrid that is worth visiting, and there are many bars, cafes and restaurants close by.
I would highly recommend this apartment to anyone that wants to visit Madrid!
