Our experience at Gisely's was very nice, the flat is lovely and has everything that you could need for your stay. Also, Gisely herself was very prompt to help us with any issues we had (we had a little problem with the gas but it all worked out in the end, and we forgot our keys once) which was very very useful. The only 'bad' thing I have to say about the flat is the noise, which is really loud at night, and that I wouldn't recommend the place for people who are not very keen on being around the busy nightlife of Lisbon. However, if that isn't an issue then Gisely's flat is a perfect choice, as it is very centrally located.
