Polash is a really nice person and gave us a warm welcome, offering advices regarding public transports and giving us a map of the city.
Despite that, the stay was not as good. The wifi in the room was awful, and the bathroom was not very clean.
At the check-in we were told that we could enjoy a free breakfast in the bar just beneath the bnb, but it was closed the following day and Polash didn't warn us.
The adjacent room had noisy guests (that's not Polash's fault, but I still think it's good to know that you can hear pretty much everything: either they were noisy or the walls are very thin).
The room was big and had a balcony and a mini fridge.
The bed was very comfortable.
The bnb is just a 15 minutes walk from Termini, that was nice.
