My husband and I stayed 5 nights at Alfonso’s home. He is a great host, he will gladly help you plan your trip if you like and give you recommendations on places to eat and they were good! Alfonso always make sure you have good stay and everything you need to stay. He is very nice and polite and so comfortable to be around but yet he will give you enough space and privacy you needed. His home is very nice and very clean and looks even better than pictures. The location is perfect, 10 mins walk to Atocha and you can walk everywhere you need to see from his home and if you need a bus and subway it right there, too.
We would highly recommend single or couple travelers, this place is a perfect stay.
