I shared the apartment with my brother and we had a great time.
We both agree, that the flat is the perfect starting point for having a great time in Lisbon, and the view from the balconies is awesome.
The communication with Rodrigo was easy and he always tried his best to help us as good as possible.
The apartment by itself was exactly how described and also very clean.
It can get a bit louder at night, because they are many bars around and always a party at night, but (at least for us) it wasn't a problem at all. We could still sleep pretty fine.
I can definitely recommend this flat and book it again!
