Ricardo's flat is well located, near various forms of public transportation, as well as grocery stores.
It's clean and is very spacious (two big bedrooms, and a big living room, though the kitchen is a bit narrower than I'd like) and well set up (good beds, plenty of living room furniture, kitchen has everything I needed for cooking, etc).
Ricardo's mother (Margarida) met us when we arrived, and was very helpful in explaining what we needed to know; also when we left the flat and I accidentally forgot my smartphone in the living room with no way to get back in, she came over right away!
The only real negative is the planes which fly over the flat much of the time. Not a big deal for a vacation flat, but worth knowing.
I would recommend this flat to vacationers with children, who need a bit more room than many flats.
