Mario's place was quite impressive. cute, clean, very very safe. I had everything I needed, and as a host Mario is eager to help and wished me a pleasant hello and goodbye, even though I never met him. location of very good, close to vatican city, metro shops and restaurants. the only thing I would say is that it can be noisy. it is just the type of building that echoes and nothing can be done. guests quieted down however in a timely fashion and when I was worried they may not, I messaged Mario and he told me to not hesitate in contacting him if they continued, as he would likely be able to message them and ask them to quiet down (it was still early so there was no need then to ask them). All in all, a lovely experience and I would stay again. Thank you Mario!:D
