First rate! We arrived to two coffee cups and two bottles of water, an immaculately made bed, and a personal greeting from the host. The apartment was spotless, to hotel standard. The sofa and bed are extremely comfortable, and although the flat is very small, as it says, the bedroom is actually rather spacious, with very effective air conditioning. The kitchen area has everything you need to make a meal, and there's a decent coffee machine as well, complete with a good supply of capsules. The bathroom is a little small, - wet room style with rainfall shower - but this is nit-picking.
Diego was an attentive host beforehand, checked up on us after we had arrived and then left us in peace. He was helpful with local recommendations for good and supplies.
Highly recommend Diego and his "little house" which is fantastic.
