Beautiful, spacious, modern 2nd floor, two bed flat in Belem with views of the river, near to a supermarket and a bakery selling breakfast and good coffee.
The kitchen was well equipped and beds were comfy.
The tram to the city centre stopped right outside the front door and a 10 minute walk took you to the train station and Belem ferry.
We spent time in Belem, Lisbon, Cascais, Sintra, Trafaria, Carcavelos and Tomar which were all easily accessible.
There is a good running/cycling path along the river and Belem Tower, the CCB, the botanics, the museum Marinha and the monastery were all great places to visit as was the Belem bakery.
Would highly recommend Gonçalo's place.
