The room itself is lovely - not anything fancy like a hotel, but cosy, spacious, and homely. The toilet is shared with other guest(s), but that is generally not a problem at all.
Location-wise this is somewhat out of town centre, but access to the metro is easy and you could even walk into town if you felt like it (approx 30–40 mins - make sure you drop by Jardins do Palácio de Cristal on the way).
The best part of staying here, though, was the hospitality. Elis and her parents are never intrusive, but genuinely care about guests: the breakfast is the most obvious manifestation of this (with all sorts of edible treats, during my stay there was homemade curau de milho), but there were all sorts of thoughtful bits which made me feel truly cared for. I am very glad to have stayed here!
