NO.1 Patrick and his mother are fantastic hosts, really going the extra mile to make your stay excellent.
No.2 The place was super clean.
No. 3. The apartment is indeed funky, and has a narrow stair, so it's not a great place if you are elderly or have balance issues.
No. 4. The apartment is in the heart of Trastevere which is great for many reasons. On thursday and Friday nights there was loud music coming from a club nearby. We weren't bothered at all-jet lagged on night one and slept through it, and out in the area on night two. But if you need a quiet place to sleep on thurs-fri, then you should perhaps look elsewhere.
But overall we loved it here!
