This place is definitely really cute. There are many positives:
- the location (Principe Real is very close to downtown but not so noisy at night; however it is on a hill, so be prepared to climb up! The closest metro stop is Avenida, but one really needs to go down the hill to reach it, so on the way to the apartment it's not the best choice. The easiest one --but not closest-- is Rato)
- the place itself has a very nice living and dining room, which is small but really cute. The kitchen has pretty much everything, including many appliances.
There are some mild negatives, which are not really negatives, just maybe make this place a little less uncomfortable.
- The bathroom with the shower is really small, and the shower runs out of hot water quite quickly. So unless the first person showering doesn't take a 5 minutes shower, the second person probably won't have enough hot water...
- The bedroom in the living room essentially just holds the bed and a suitcase. But it may be too small for two adults, if they have many things to store.
So in the end I would definitely recommend this place for a short stay of 4 adults; but for longer stays 4 adults seem too many. Maybe it would be perfect for 2 people and a child.
In any case, we had a very nice stay. The hosts are really nice people and always reply really quickly. Moreover we had a child with us, and they gave us all we needed (highchair, crib and also a stroller!)
