This apartment was perfect for our 3-people stay during a weekend in Lisbon. It is very well located, only a 15 min walk or so to the city center, or 30 minutes to the castle. It is also well connected via public transport. The house is pretty clean, we saw the cleaner leaving just as we arrived!
The bedrooms are well sized and the mattresses are comfortable. If you have a neck problem like me, you may want to bring your own pillow.
