Luis was super friendly, helpful, welcoming, and responsive-- everything you could want in a host. Seriously, cannot say enough good things about interactions with Luis. I think my only issue with my stay is something that Zuzabed could not help: I came at a time when there were heavy rains and my room smelled like mildew as a result (I had the room with the two twin beds). Luis was very sympathetic but unfortunately could not move me because he was fully booked. That is a minor complaint-- truly, overall I wholeheartedly recommend staying here. The location was fantastic-- easy walking distance to tons of areas (Baixa, Barrio Alto, Principe Real) as was the service.
