The place was excellent - the view cannot be described with words or pictures.
15 min walk to vatican and most sites - we only walked for all the days we were there - didnt even use the metro. The hill up to the place is quite steep but very very doable - we walked up it everyday.
Marco was extremely responsive and accomodating and gave great recommendations.
Yes the roof is low - but trust me - the view makes up for all the small little things you may read about
