Parrotshouse was a nice apartment perfect for my wife and I's 4 night stay in Rome. It was clean and well decorated.
Francesco is very helpful and made checking in easy. We arrived late but we were able to use a code to get in and Francesco arranged a time the following morning to complete check in and provide us with plenty of tips on sights to see.
The apartment is a great location for the coloseum, Spanish steps, Trevi fountain and Termini Station. Other sites are a bit further out but still easily walk-able if you have the time. There is also a metro station a few minutes away which can also make getting around easy.
Would recommend :)
