The place was clean and not badly equipped (a cutting board would be very useful, for example).
The location is great. All attractions accessible by food, at night the traffic (especially tram) can be noisy, not to mention occasional ambulances with sirens on since the flat is next to the hospital. So, these noises my disturb the sleep.
The host. It is written that he is able to speak English. OK, maybe, but I didn't experience it The only way we communicate was via e-mail. I wrote the message in English and got replay in Italian! Luckily, the google translate works pretty well and I also understand some word in Italian. So, with a help of my wife and daughter, we managed understand these messages even better.
His response: before checking in, I tried to call him on the provided telephone number several times. No response! On Sunday, we hade to leave the place one day earlier due to health problems of my daughter, so I wrote him an e-mail and tried to call him. The telephone was death and an e-mail came several hours after we already left the place (of course, I was not able to read it while driving back home).
