My girlfriend and I stayed at Lorenzo's place in Rome for 3 nights in late March and had an amazing time. He was able to greet us at the Roma Ostiense train station when we arrived around 10pm which was an enormous for our first time in Italy.
The place itself is as lovely as the pictures show. It is safe, stylish, and in a GREAT location. 5-7 minute walk the Roma Ostiense and Piramida train stations and a 15 minute walk to the Coloseum. The first day we walked to the Trevi Fountain and Villa Borghese. The next day to Trastavere. The third day we decided to take the train to the Vatican. All options were great. If you want to get some good walking in you can, if you want to take the train you can. There is a wonderful restaurant within a 5 minute walk called The Donegal 2.0. Don't be fooled by the low yelp review of it, the food and staff were great. There isn't much else around the home so having The Donegal (which stays open until 2AM) was great.
In addition to the place being fantastic, Lorenzo was incredibly hospitable. He helped carry my girlfriend's bag up the steep hill to the house. There was a bottle of wine waiting for us when we checked in. He gave us a map and texted me 5-6 other recommendations to check out. He answered any and all questions we had and went above and beyond to help us with anything we needed.
The details in the description are 100% accurate. If I HAD to criticize something, I would rate the bed 4/5 stars, nothing a foam topper couldn't help. Everything else was perfect. I did a LOT of searching on AirBNB for places in Rome and I would recommend it to anyone looking for great price + great location + safety + comfort.
