We had a lovely stay in Principe Real Guest House 2. Everything was exactly like on pictures, the apartment is fully renovated, fully equipped, spacious and cosy. The location is great - in heart of the city, perfect for sightseeing, you even don't have to use metro, as some attractions are within walking distance, there are many restaurants in the neighborhood as well.
Joao was very helpful, the communication with him was very good ans fast.
I can fully recommend this apartment:) I would stay here again if I were in Lisbon again.
