Celso is a great host. He was really helpful in providing instructions on how to find the apartment, met me there when I arrived and also gave great recommendations of things to do in Lisbon.
The apartment itself is really well located and close to lots of transport links. The room was clean and comfortable and the apartment has all the facilities you would need. The only thing to note is that the room faces on to a fairly busy road so could be quite noisy for light sleepers, but I did not find this a problem.
Overall a great place to stay - thank you for your hospitality Celso!
