3 things made me give the top grade: perfect location of the studio + great communication system with the owner + nice studio.
Nuno's studio is is located in an absolutly perfect place for those who come to Lisbone just for few days and want to see as much as it's possible. It's super close to everywhere; even to a small supermarket ;) Besides we had no problem with communication before and during our stay. Nuno answers super fast on every question. Studio itself is nice and equipped in everything, that is necessery.
I certainly recommend it to everyone.
