This place is difficult to rate because I think it can be a great place when Renata is around. In my case, though, she wasn't, only her mom.
Her mom not only does not speak a single word of english, she also seemed inconvenienced by my stay - often barely saying "hello" etc. - making me feel very unwelcome.
If you plan on staying here, I'd make sure Renata will be there as well, or that you speak Portugese
