I had a fantastic experience staying in Ale's home. It is right in the center of the La Latina neighborhood between two metro lines, which makes it very easy to get to pretty much anywhere in the city. There are also many restaurants and bars within walking distance. It's also only blocks away from the infamous Rastro market that occurs every Sunday.
Additionally, Ale was a great host! She has a very cute space and was very accommodating. She recommended events where I could practice my Spanish and meet new people. Her two cats were very friendly. (I would recommend bringing a lint roller for the cat hair though).
