The stars are for the location, the terrace and the hosts: the communication was very good.
Nevertheless, my stay was not good at all and I even spent 2 out of 4 nights in a hotel because the mattress was really bad. I had really uncomfortable nights. I complained to Marta and Paul (too late, I must confess) and they replied that the mattress was fine for them and the other guests who slept there before and after my stay. In the end we have different opinions (which is normal), but I would not recommend this flat in the current conditions.
Best,
Marco
