I stayed at Mouzinho 134 for more than one month and I have left with only most pleasant impressions: the apartment is just as nice and neat and clean as it looks on the pictures, the whole historical building is nicely renovated (in respect to the authentic features), and it has plenty of "portuguese soul" in it, just like the rest of the neighbourhood. Of course, living in an old authentic house implies certain differences compared with modern buildings, for instance, hearing your neighbours much more, but I was not bothered by it, in certain way, it is part and parcel of the "charming old authentic portuguese home" feeling, which I fullheartedly enjoyed.
The hosts are incledibly welcomming and helpfull and friendly, Eugenia went to great lengths to accomodate any requests or needs I could have during my long stay, which I could not thank her enough for!
All this combined with the wonderfull city of Porto made an unforgetable stay. Thanks again!
