Alex is a great host! He is good company and chatty about anecdotes and more.
The house was every day sparkling clean and the location just perfect, Lapa is a great district with a lot of cafes e nice restaurants. Santos train station is only a 10/15-minute walk.
I stayed in the single room, that would work for a short stay, but if you stay for a longer period of time I'd recommend booking the double room :)
