Ana and Luis were amazing!! They were both incredibly pleasant people and the room they provided us was really nice. They provided a lot of information about the surrounding area which was very helpful for my girlfriend Lindsay and I. Luis also speaks a little bit of english, which I found helpful. My Spanish is not as good as Lindsay's.
If my Spanish was better and if we weren't running around Madrid so much, I would have liked to spend more time with Luis and Ana as they are very friendly and invited us to hang out with them a few times.
Overall a really great experience.
Also if they offer to pick you up from the airport, you should take it. Taxi prices from the airport are crazy.
