Gonçalo has been a great host. We checked in at 10:30 pm, which was absolutely no problem (as well as the check out at 6am). Gonçalo already waited for us at the apartment and helped us to carry our luggage up to the 3rd floor.
The apartment is well located in the middle of Alfama with a great view on the river. It was very clean and Gonçalo put up a vent to beat the heat (~35 degrees celsius during the day), which helped us to cool down after a long day of walking around in the city.
We can recommend a stay at Gonçalo's apartment at any time and would be glad to come back.
