Manuela is a perfect host! We were at first a bit concerned when we approached the place because it is on a bigger cobblestone roads in Porto. However thanks to double (or triple??) glazed windows, you didn't hear any street noise and so the location is perfect: In the centre of the centre, as Manuela described it. Everything is in walking distance.
The space was much bigger than we expected and all amenities (kitchen, bath room) was modern and ultra clean.
The check-in was easy and Manuela gave us some very good restaurant recommendations: Insider tips which were real insider tips and not already published in the Lonely Planet ;)
