We spent 4 nights at this place and it was truly amazing. Viktor is a very nice and helpful host. It was always easy to reach him and he answered every one of our questions.
The accomodation is a separate, light room, which has its own balcony and bathroom and a shared kitchen. Every space was cleaned. It's well located, literally 5 seconds walk from Campo de' Fiori, the big market place where you can find everything you like, and even more. There are a lot of shops, bakeries, pizza and ice cream places around every corner. A lot of monuments and other things are not far from the apartment by walk, and even if they are, you won't notice it because there are so many things to see.
I can only recommend it.
Thank you Viktor once again for having us, and being such a nice and reliable host, I'll definitely try to go back if possible. :)
