I stayed in Goncalo's place for 4 days at the end of September. I think it is one of the best locations that can be stayed in Lisbon. It is super central, close to everything you need (Public transport, nice restaurants, night life..). Plus, the flat itself is amazing with the characteristic design & helps you enjoy the limited time that you stay in there. It is worth mentioning that, although the street of the apartment is busy with bars & generally quite noisy at nights, the bedroom is located in a really good place that you do not hear the noise from outside. Last but not least, Goncalo is really a nice host. Right after my reservation, he asked for a transfer from the airport & shared the detailed address. Then he also shared several tips on Lisbon (The magazines in the flat were also quite useful). He really gives you the feeling that you can ask for his support for any issues. Overall, I would really recommend Goncalo's flat...
