The stay at Frederico's was great. The location is perfect, near everything you would need during a vacation. The apartment itself is charming, in an old building, but the apartment is entirely refurbished. We were 4 adults and had a great stay : the beds are big enough and the bathroom is nice and recent. We didn't use the kitchen that much but it's very well equipped. For very hot nights, there is AC in the apartment, we didn't have to use it in our case.
Final word for Frederico, we didn't have the occasion to meet but he has always been nice and very responsive.
Overall a great place to stay, where I hope to come back in the future !
