It was an absolute pleasure staying at Roema Guest House.
The check-in was seamless thanks to their detailed instructions. The room and our private bathroom was sparkling clean on arrival. We had a shared kitchen and though it didn't have a full on working oven, they did provide a couple of portable heating element that was enough to brew coffee and cook eggs in the morning. The 24/7 grocery store is minutes away though keep in mind you would not be able to cook a full meal with those portable heating element. That is hardly a problem as you will find relatively cheap yet delicious meals all over this town in a walking distance. Heck there is even a fruit shop (which is very affordable) if you wish to gorge on some fresh morsels. The room has an AC unit that is a good relief from summer heat outside. There was a closed metro station(Cipro) nearby due for opening after we leave but even so, you will be able to find bus stops nearby and the second closest metro station (Valle Aurelia) around 15 minute away.
There is much to be said regarding the mannerism our host. The house keeper does not speak English but she was very friendly and didn't seem to mind when we asked for refill on some of our amenities. Roberto, the host, was very courteous as well. We had to make adhoc extensions to our stay at the very last moment and we were easily able to work it out with him without any issues. There was an incident where someone drank some water from the shared fridge (mistakes happen) but he immediately responded by letting the other tenants know and came in the next morning with a whole six pack of new water! We tried to politely refuse it, as it was just one bottle, but he was very apologetic and really wanted us to have it so we ended up taking it at the end.
Additionally, they were very helpful when we had a "situation". It was a Sunday so we didn't have a good luck finding a ride to our airport the next day and when I messaged them with our dilemma they immediately booked a taxi ready to pick us up at our time at the mandated local rate. That was almost godsend.
All in all, for someone who randomly clicked around to find a good place to stay for a Rome trip, it far exceeded all expectations.
