We spent a really nice short stay at Diogo's apartment. The flat is as in the pictures, it is really well located in the heart of the historical Alfama and easy to access.
It is very clean and well equiped. Everything is provided: towels, kettle, Wifi :-), some amenities in case you forget your shower gel, also coffee / tea for the first morning. A really nice bakery (convenient for bread / pastel de nata ;-) ) is just a short walk down the street. You also have a lot of restaurants / fado in the neighbourhood but it is quiet during the night.
