We had a nice stay in this home. This apartment is extremely well located. It is near train, bus, restaurants and almost every interesting spots in Lisbon by walk. It was really useful!
Certain things should still be considered: If you are five people and one needs to sleep in the folding bed, just be aware that it is not the most comfortable. But still, I slept on it the whole stay and I was fine! Also, some facilities were not present in sufficient numbers (ex. toilet paper). But you could buy the things that were missing in the store in the street.
In short, we enjoyed our stay in this apartment. Thanks !
