Marco might be the best host I've had, and I've used Airbnb a ton over the past four years. He is extremely detailed, well-organized, and quick to respond.
Everything in the apartment works flawlessly. It's easy to tell that Marco puts a lot of time and effort into maintaining a high standard. It's a good layout, stylish, and functional. There are multiple heat and/or AC units, an easy-to-use washer, fast wifi, great shower with lots of hot water, and a plethora of soap and other toiletries. The bed was big and comfy, with a nice warm comforter.
The Colosseum is about a 12 minute walk away, and there are numerous food, coffee, and grocery places within a short walking distance. Marco's food recommendations are impeccable, by the way.
Overall value, quality, and experience is unbeatable, in my book. You'd be hard pressed to find anything that can compare.
