Rui's sister welcomed us at our arrival, even if she was a little late and we didn't know that he was not supposed to come, she was nice and helpful and gave us her advice about the best restaurants and places to visit in Lisbona.
The flat is very, very small but comfortable and well organised. There is a wonderful view from the window, we loved the small "altana" on the upper floor!
You have to climb two steep (very steep!!!!) Stairs to get to the flat.
The bathroom was a little bit smelly and there was no paper toilet when we arrived.
Anyway, we really enjoyed our stay in Rui's flat and we would really recommend it.
