Tina was really a great host! We arrived earlier than expected but she had no problem in opening the house for us some hours before. She also had us some cantuccini (traditional biscuits) after the first night and allowed us to leave the backpacks in the house for the whole day after checking-out. She is a very helpful person!
As for the apartment, it was fantastic and very clean. It had all what is reported in the advertisement plus coffee, tea, pasta, juices... that you can take without extra charge. There's only telephone signal at the entrance of the house, but the wi-fi works really good. There are stairs to go to the kitchen and to the toilet, so it might not be really suitable for persons with mobility problems.
The location was also perfect. Close to the station and all the touristic places.
I would recommend this place, and I will repeat for sure if I ever go back there :)
