I had a wonderful stay at Guillermo’s place. I stayed in the apartment for about 2 months while on a work assignment in Madrid and it was perfect. The location is great (2 minutes to plaza de espana), the apartment is extremely spacious compared to other comparable apartments in the area and it was very clean. Guillermo was very responsive as well and check in was a breeze. The apartment was great value as well compared to my previous Airbnb in Malasaña. 5 stars!
