Sofia's place was exactly as I expected. Very nice, and clean. It's comfortable and in a great location in regards to the universities, metro stations, downtown. It is near the airport, so there is a little jet noise, but it did not bother me at all. Sofia communicates early and often. The place is a little difficult to find at first, at least difficult to find the correct entrance. Sofia and her mom were of great help though in locating. Wonder experience and I would book again next time I am in Lisbon.
