My wife and I could not have been more impressed with Alejo's place. Though we never actually met Alejo, he was very easy to get in touch with and quick to respond to our questions. His partner Julian, who let us in and showed us the place, was extremely friendly and helpful. The location of Alejo's place was perfect - so many great sights within walking distance and there are tons places to get food nearby. The apartment itself was in great shape and very comfortable for the two of us - my wife and I felt right at home. The breakfast and coffee each morning was a plus, as was the air conditioning and cleanliness of everything. We had a late train out of Madrid on our last day in the city, and Alejo was nice enough to let us check out a bit later than 11 - and he even had his friend hold our bags until we were ready to leave, so we could continue to explore Madrid without having to drag our bags around. We would definitely recommend this place, and would stay again should we ever find ourselves in Madrid.
