Simply put; I LOVED staying at the flat and I wish I owned it. The location is just perfect. I basically walked to both the Colosseum and the Trevi Fountain. There's also a train station minutes away. This has truly been my favorite AirBnb experience so far.
The pictures don't do the place justice whatsoever. Everything is super clean and you immediately get a warm and cozy feeling upon entering the flat.
Having the Moka pot (+ coffee) at my disposal to make a brew the Italian way was a nice touch (and saved me a few €uros as well). There's an umbrella you can use as well on rainy days.
Costantino is very warm and welcoming. The check-in/out processed were seamless and he gave me a walk through of the flat. The only think I felt a bit weird about was him needing to take a picture of my passport. I had yet to have a host make such a request before.
