We (my girlfriend and I) spent four nights in Renato's cosy flat in one of Porto's main streets. During our stay, Renato was attentive and very helpful, giving us great tips of not-so-touristy restaurants and places to go around the city. The flat is modern and comfortable, with a lot of light, a lovely garden to enjoy on sunny days and an incredible (large) bedroom! We even got to taste the delicious Porto wine he had left there for us. Renato did his best to make us feel just like home.
We strongly recommend this flat!
