The flat is amazing, well eqipped with anything you may need to enjoy your stay in Lisbon (including a welcome breakfast and loads of travel guides). The location is perfect, in a nice historic area and close to many sights and also to the metro, bus and tram lines.
Teresa was really helpful in giving us suggestions and recommendations for what to see, where to go and how to get where we wanted. Moreover, our plane was delayed and we arrived to the flat around 4AM, but she was still there waiting to let us in, which obviously meant a lot to us.
Highly recommended and we would definitely stay there again!
