Me and my girlfriend stayed at Bella Nina for 1 night only.. They had some problems with our reservation and had to change us to a better room, which was nice, great views to the Forno Beach. The bed was comfortable, the bathroom is ok, but the room was poorly cleaned, there was hair on the bed cover, the mirror in the bathroom had thoothpaste spits and there was a dirty towel left behind from the previous guests. Our AC (that is not a split, so very noisy) was not working when we arrived, so we had to wait for the owner to fix it. Talking about the owner... I don't understand how this guy runs a Pousada, he's very rude, not receptive and not willing to help you at all. Perhaps if you are also an Argentinian he will treat you better!
Breakfast is terrible, juice from the box, bad quality breads, the fruits were covered with insects, they don't really care... would be better to eat at the gas station on the corner!
So we do not recommend Bella Nina, I bet there are better options for the same price!
