Roberto was a very responsive and flexible host. The apartment is charming, modern, and very nicely equipped (I especially liked the sheets and towels, and I'm very picky!), the building is also very charming, if perhaps just a bit down at the heels. The Roma location is absolutely perfect, it's a fantastic neighborhood. All is as advertised. But there were a couple of down sides: no hot water to speak of (the hottest it got was lukewarm), and bothersome mosquitoes at night.
