Emauele's apartment is very near the Metro station. You need to travel a bit from Roma Termini but its a direct line for about 20 mins so it's not at all inconvenient. The room is big and clean and Emanuele is generous with the beverages in the fridge. He speaks good English which is important to us.
The only small inconvenience is that the bathrooms are shared so when there are other guests, you may have to wait for your turn. However it's not a big deal since we all use the bathroom at different timing.
