We stayed here for two nights the first of August. Luis was a great host, helping every way possible - met us on time and let us in, had suggestions of restaurants and points of interest, gave us the architectural tour of the studio, - even had fresh squeezed orange juice in the fridge for us upon arrival. The studio is small which is typical for downtown Porto but has everything you need and is in a great location for getting to all the major spots. The only downside is that there is a very popular ice cream store directly below which stays open late and has long lines and since the studio doesn't have AC, you hear people talking until late. Other than that - it was great!
