Mario's place is fantastic. It's in a great location - we walked to everything and it feels like you're surrounded by locals. The apartment was on a canal, so it was great watching the boats go past morning and night. It was not noisy, didn't smell and was lovely and clean. Mario is very friendly, and recommended some great restaurants (including one where I had the best pasta I've ever had in my life). We are so glad we found this listing, and would definitely stay again!
