We had a really comfortable stay at Roberto's place. He is very professional as a host and he does this "job" perfectly. The room and the apartment in a whole were very clean and had everything that quests can need. It was totally corresponded to our expectations based on description and photos. Special guide provided was very helpful and professional. So, we are very satisfied with our choice and hope will come back soon. I recommend to stay in Roberto's place to everybody who wants to feel real Spanish environment in quite business centre of Madrid :)
p.s. Thank you, dear Roberto!
