Andrea's place was perfectly located. It is next to the Colosseum and near a 24hr market and main bus route, which are incredibly convenient. Note: bus tickets cannot be purchased on the bus. The apartment itself was just meh (i.e., unexceptional). While it was clean, it was a bit dated and barren. The stellar reviews had me expecting so much more. As a host, Andrea was very responsive and accommodating.
I was a little put off by the framed sign in the washroom stating the various penalties for blemished linens. Not exactly a charming touch, and easily could have been included in the welcome email, listing, or contract Andrea requires you to sign and return to him within 24hr of your arrival.
