Location: Very good location to visit the Vatican (10 minute walk) and the spots surrounding it and only a 15 minute walk to the A (red) metro line that can take to many of the other sightseeing spots. If you walk a bit further (~30 minutes) you can hit most other tourist locations as well. The apartment is right above a nice restaurant and walking distance to many others. A grocery store (Carrefour Express) is a 10 minute walk away if you need to stock up on any food while you're staying in Rome. Area felt safe and we walked home late nights and didn't feel unsafe at any time.
Space: Very nice and spacious apartment that was generally clean. We fit four people with room for more if needed. The private balcony was a very nice touch, and a good spot to have some wine after a long day of walking. Both bathrooms were nice, although the hot water wasn't as hot as Americans might be used too. A full kitchen if cooking is your thing. Beds were comfy and enough linens and towels were included for me and my my family. WiFi was easy to connect to and sufficient for browsing/tiktok/work but we didn't try to stream videos.
Host: Easy to communicate too with quick responses. I didn't have to wait at all during check-in. Gave an overview of the house and showed us how to use the stove, etc and connect to Wifi.
I would stay here again if I'm ever back in Rome.
