Very much enjoyed our stay at Paolo's place, which is ideally located one block from Termini Station, which has a 30 minute direct train to/from FCO Airport. Paolo met us right on time and even helped us haul our luggage up the stairs (no small favor since we had already stocked up on wine in Tuscany!). The apartment was exactly as pictured and super comfortable- we slept wonderfully. We really loved the cozy lofted bedroom, but taller folks might have to watch their heads as the loft ceiling is low (I'm 5'7" and just cleared it). The kitchen had everything we needed to prepare full meals, and there's a full service laundry place around the corner (10 euro for a large load). Thanks to Paolo for a great stay!
