We found communication with Roberta to be difficult. She did not respond to my messages until two days before the trip. She was not there to check us in and when we called her upon arrival she said she would be there in 15-20 minutes. We were waiting outside the apartment for 40 minutes before her husband arrived. He seemed more concerned with getting us to pay the tourist tax than showing us around.
There were a few other frustrating things. The WiFi only worked properly in the sitting room. The toaster didn't fit into the plug and you had to turn off the air con if you wanted to use the washing machine or dishwasher. The shower was faulty and went from hot to cold. There were only the most basic amenities available.
On the plus side. Roberta was quick to reply when we had a power outage and helped us fix it within 5 minutes.
The location was fantastic. The apartment was located in a really lovely area of Florence.
