Rossella and Rossella's place were wonderful. We would stay there again in a heartbeat.
Physically, the unit is spacious, full of light, private and quiet. The patio is off the charts excellent whether its reading quietly in the morning or for an early evening glass of wine. All the amenities were spot on (high quality washer/dryer, very functional kitchen and really nice bathroom).
I will echo previous comments about Rossella's hospitality. Excellent communications, warm greeting (with a nice cake to boot!), thoughtful tour of apartment etc. Was kind enough to book a taxi for our 430am departure.
The location is workable but is a bit further from what we wanted to do than is optimal. Probably doesn't help that Rome's public transport is just fair compared to that of many other major metros.
