Alfonso’s place was great! The location is amazing to do anything you want in Madrid. There’s also a metro/subway stop right near by to get around even further if you wish. The only thing I would note is that it is one of two rooms he rents out; so you could be very lucky and get someone great or not. Shared bathroom for all. However, I am a young 22 year old female and felt comfortable the entire time and had an amazing stay.
