Agustina is a great host. She was understanding when I arrived a little later than expected and was immediately generous with her space. I enjoyed talking with her! The room was very comfortable and clean and the private bathroom was a huge plus. It was very hot in Madrid, but the air conditioning worked perfectly when I needed it - and most of the time simply opening a window at night was enough. The building was also very quiet and the area felt safe as a solo traveller, with really easy transport links to the centre (both bus and metro). It's true that Agustina does ask that guests follow a few simple rules about keeping things clean, etc, but these seem reasonable, especially in someone else's home.
