Me and my girlfriend spend two nights in Rui´s flat and it was a really nice stay.
Rui met us at the apartment and showed us round the place and answered our questions in the kindest fashion.
The apartment was really nice and had everything we needed. It had a really nice bedroom, a nice and well equipped kitchen, a nice big bathroom and a cool living room.
Everything was clean and nice when we arrived and we felt really relaxed during our stay.
The apartment is placed in the north part of Lisbon, which is nice and quiet during the night, and is within walking distance of the central Lisbon and the more vivid part of town. It is close to the Park Eduardo VII which is a nice place to chill and enjoy a great overview over the city.
It is also very close to the metro going to and from the airport, so that is also a plus.
All in all we had a great stay at Rui´s place and I can only recommend it highly.
