We had a really warm welcome and the whole communication before and during our holidays was perfect! David answered very quickly and also gave us some tipps what to do in Lisboa. The apartment is perfectly located, although it can be a little bit noisy in the evening/night, but you just have to go party yourself, then you don't mind ;)
The size of the apartment is perfect for 3 people and it has everything you need. Furthermore, there is a very cool rooftop bar nearby, a lot of restaurants and also the Mercado da Ribeira, which is absolutely lovely (there is also a shop from Manteigaria, where you can get the delicious Pastel de Nata, without waiting that long as in Belem)!
We really enjoyed our stay in Lisboa and at David's!
