We had a pleasent stay at Sofia's apartment. The flat is very well located, not far from downtown and close to the metro. We had everything we needed and the flat was nice and cool even in the middle of a hot day. It is on the ground floor, so the bedroom windows face the road, which also makes it a bit noisy. Check-in was later than we planned, but during summer might be expected.
Overall it was a good place to use as a base to spend a holiday in Lisbon.
