Location. Location. Location.. The location of the apartment is indeed unbeatable - right in the center of everything - allowing for easy access to all the major Rome attractions and most within walking distance.
Ermanno is a great host and very welcoming. He is easily accesible and responded to our requests and questions rapidly.
The apartment can accomodate up till 7 people if bed sharing is not a problem. Only 1 bathroom as stated.
Despite the good, there are some issues you shoud take into account:
1. We came during July and daily tempuratures reached 37 degrees Celsius. The 2 portable air-conditioners had a hard time keeping up with cooling the house under these conditions. It was hot inside despite use of these units - even during the night. Ermanno came to our rescue with additional fans which helped a bit to dissipate the heat.
2. As the building was built many years ago, and as Ermanno told us, the electricity couldn't handle more than a few appliances running at once and the circuit breaker would drop. So for instance, to use the washing machine, one of the air-conditioners had to be turned off.
All in all, Ermanno is a great host and living in the heart of Rome was an amazing experience.
