Lelio & Giulia's place was amazing. It seriously felt like we walked into a hotel suite. It was very comfortable, everything is nicely arranged, and it is extremely clean (says my wife who use to be house cleaner). And it odd pretty close to the metro- about 3-4 blocks away. If it is available you must stay there. My wife and I visited 4 different Air-b&b places in the last 3 weeks and there's was by far the best. The bed is super comfortable (the most important thing to me). There was plenty of closet space and a desk in the bedroom if you needed. The kitchen/dining/living room is also very well organized. They had all the cook ware you would need to cook. The gas stove and dishwasher are both new. The fridge/freezer has plenty of space if you want to get some things at the supermarket which is only two blocks away. And Lelio and Giulia prepared a really nice welcome booklet that is in both Italian and English. In the bathroom the shower is very nice and there is a washer that works well too. The AC was super nice as well.
Also, Lelio and Giulia are very attentive and helpful if you need anything. We had a little trouble with the WiFi (completely our fault) and when I texted them they responded right away and helped us out. They also helped us with suggestions and tips. We were able to meet them and chat for a bit- they are a very lovely couple.
