We stayed at Juan's place for a couple of days- the apartment is great, Juan is a great host and very easy to communicate to- he gave us a good local tips for where to go, where to eat and even made a reservation for us at a restaurant. The location is great, in front of the apartment there is a subway and bus station so the public transport is always an option (although we went almost everywhere by walking-the apartment is at good walking distance from almost everything).
We also had a private bathroom (which is always a plus).
Great experience- we are definitely recommending :)
