Overall, our stay in the apartment was average and inconvenient.
Isabella was an excellent host and extremely proactive communicator. She responds to messages very promptly, offered tips and even helped arrange an airport taxi for us.
However, this by no means compensates the inconvenience we had during the stay. The water heater was faulty and only provided hot water for 5 minutes after letting it heat overnight ~8+ hours. This was especially difficult since Rome is cold during this time of the year and we had no choice but to shower in cold water. And the inside bolt of the main door is old, requiring a lot of force to open, resulting in us being locked out for an hour. Also, the check-out process is extremely tricky and leaves guests at high risk of being locked out by the front door or gate without the keys.
Interacting with Isabella was definitely the only saving grace, making this place quite low value with lots of room for maintenance and repairs.
