I stayed in Patrick's place only for one night with 5 other friends. We really loved the style and quirkiness of his place. It was clean with extra towels and bed linen provided and a great location, within a half an hour walk of most of the main sites in Rome and plenty of restaurants nearby. Patrick was a great host and his communication was good with quick responses via whatsapp.
One word of warning, if you or your party are less mobile, please be wary that the two bedrooms on mezzanine have low ceilings so you have to bend down to get in. For us, a big group of young guys this was no problem however.
Thanks for a great stay Patrick!
Ciao.
