Despite the language barrier, Alfredo was very easy to work with. We didn't see him much while we were there, but pre-arrival he kept the lines of communication open and made sure that check-in was easy and efficient. His place is a great find, actually. The apartment is lovely and the guest room is on the opposite side of the flat from Alfredo's. It does share a wall with another roommate, however. Lastly, it's in a great location near hip neighborhoods as well as a short walk to Madrid's city center. Over-all, a great spot for your stay in Madrid--especially if you are a Spanish speaker (so you can chat with Alfredo more!).
