Ana’s place is absolutely fantastic. Everything is thought of and the welcoming touches are very considerate. The apartment is about a 20 minute walk to the Termini station and about 30-35 minutes walking to central Rome. The Colloseum is less than 20 minutes away. It’s really well appointed with a good kitchen (with some essentials if you want to cook), really comfy bed and big bathroom. I’d absolutely recommend staying here.
