This is a great place to stay on your visit to Rome. You are in the middle of everything, just a few minutes away from the Campo de' Fiori and nice shopping streets. Everything you want to visit is on walking distance.
There is a supermarket very near, and a good restaurant in front if the house.
The apartment is very comfortable: good shower, good WiFi, small but complete kitchen, good bed in the master bedroom. It is located in a house with a congierge, and you feel very safe inside.
The only point for improvement is the bed in the second bedroom. But the problem will be easily solved with a top deck on the mattress.
Teresa is a very nice host. You can always call or app her, and she is very responsive and eager to help you with anything. And her English is very good, so no communication problems.
When you go to Rome, stay with Teresa!
