If you want to feel Lisboa in a proper way you should definitely rent this apt! It is located inside very cosy and typical Portuguese district next to the street with stylish funicular. There are also great view and when you stand at the balcony you feel like true Portuguese because of great atmosphere around.
Samuel is honest and respectable host and there weren't any problems to communicate. However, I believe price could be a bit less. But overall this place is highly recommended to rent!
