The flat is as described, well located, old but cozy, only one flat per floor and only two flats in the building. Both, Ludgero & Joana, are very very good hosts, they answered to our questions, and helped us giving advices about the city. The wifi worked good; I write this because in other places can be unuseful at all.
The main issue in the flat i found (although described in the page) is that the toilet has no door, but a courtain, and it can be a problem for the privacity.
There are planes flying near due to the nearly airport but it was not a problem for us.
Joana&Ludgero, both, very nice guys.
