We were two persons & stayed at the apartment for four nights. The area Madragoa is lovely, very authentic and not too busy with tourists compared to the other neighbourhoods. Still all main attractions are within walking distance - we almost never took the public transportation, even when we visited the castle 'at the other side' of the city.
The apartment was very spacious, quiet & clean. Especially the water pressure in the shower & the super comfortable bed get 5 stars :))) Expect the apartment to be pretty minimalistic, though. We were missing a basic stock of e.g. spices or tea (and a tea pot). Of course that's only a small downside :)
As the apartment is on ground level you probably won't keep the front windows wide open all the time - so it's a bit darker as on the pictures, if you don't want to go by electrical lights only.
Overall we enjoyed our stay a lot. Thanks a lot to the hosts!
