Joana responds very quickly and the arrival was really easy for us. Her apartment is very nice and stylish, extremely well prepared and there are a lot of nice details which make you feel as at home. However it is really small, so for longer then 2 nights stay (which we did) I wouldn't advised it for more than 1 person. The other point is that you can hear small music from the restaurant below till 1 a.m.more or less, it is not very loud but on long term bases can be a bit annoying. Finally there is also a little problem with the light coming from the staircase, which woke us up few times when other guests were coming back home late in the night. I guess it could be resolved by covering the glassy part of the apartment's door.
Apart from those small details, our staying there were really comfortable.
