Piermatteo is very very nice. He will go above and beyond to help you with tips and information about the city, sights, restaurants, bars, he provides a map, the whole package. The place is nice and very clean, has everything you need, modernly furnished, spacious shower, comfy beds. The metro is super close and you're in the vatican in 5-10 minutes and in the centre in 10-15. Overall very nice. I even broke a wine glass and Piermatteo was very nice and understanding about it.
