Me and my husband stayed at this apartment for 4 days.
Rui picked us up from the airport, which was very nice of him. He was very welcoming and provided us with a lot of information about the city.
The apartment is situated at a good location in Baixa, walking distance to many interesting locations and close to a metro station.
Beware that there are many stairs to climb on your way :)
The apartment is cosy, with good air flow, comfortable bed and a beautiful view to the castle.
Rui provided us free portable Wifi which was very convenient for getting around.
The down side:
The size of the bathroom is small, typical to old houses, still it was a bit frustrating to squeeze in the shower and use the toilet.
