We loved Giuseppe's place and would definitely stay there again if we were to visit Rome in the future. The location is great especially if you're looking to visit the colliseum or the Vatican as it's right between them both. The air conditioning was an awesome break from the hot day and the bed was super comfortable.
Other people have mentioned noise and while like other buildings in Europe you can hear the street noise it was only a bit of an issue one night for us. There ended up being about 30 or so teenagers outside being very loud but they left right at midnight luckily so we were able to sleep without any issues. If you're a light sleeper you should probably just have earplugs for any place while visiting Europe.
