Eva and her brother was a great host, and organised a private taxi from the airport to the accommodation for a good price. We were met promptly by Eva's brother who showed us around the accomodation etc..
As a family of 4, with the two young boys being 8 and 2, the winding flight of stairs was a little slow as we had to try hold the youngest hand. The 8 yr old loved it as he was constantly reminded he was walking down a 16th century flight stairs...litterally walking down a piece of history.
The accomodation itself was perfect for us and spacious, could not fault it.
Location wise was spot on....with everything so very near, you don't need to walk far untill you reach much of the historical sights listed in the lonely planet...especially when you have an 8 yr old who constantly complains his feet hurt after 30mins of walking.
I would definitely recommend Eva's accommodation and would book it out again if I were to visit Rome again.
