Mixed feelings about our stay:
1. The apartment is amazing, really big and comfortable, we were 4 people and the two independent bedrooms with good beds are worth It. Big bathroom and comfortable kitchen.
2. I would not recommend this for a digital nomad or remote worker, the wifi is really really slow, and there mobile data also has low reception.
3. As stated in other comments, there is a problem with the boiler, we stayed 4 days and it worked 2, so we had to take cold showers which was not ideal, Sabrina tried to fix it and was responsive but it seems the technician did not fix anything.
4. The location is quite tricky, if you are going out of Roma it is good since it is near Roma Termini, but for all the other attractions you have to either walk or take a bus to reach de metro. (Although Rome public transport is not that good).
As summary; the apartment itself is really really good but there are some issues that should be fixed like the boiler and the WiFi.
