Vitor is an extremely understanding and kind person. I had an unscheduled stay in Lisbon and I've made a late reservation with very late arrival and late check out. Thanks to Vitor my situation was fully solved without any problems.
The room I was staying in was clean and neat. The apartment itself is well located, near to metro and walking distance (~15min) to the Expo zone by the river where you have a big shopping mall and plenty of restaurants and coffee shop choices.
I would totally recommend Vitor as a host and his room as a place to crush on.
