Angelo is an experienced and attentive host. He helped us book an early morning car ride to Fiumicino airport which relieved us of a lot of stress.
His apartment is nicely appointed. It is a large apartment with two rooms. The front room is more spacious but since directly over a busy popular street it can be noisy. We used noise cancellation headphones to help us sleep. In hindsight, the second bedroom removed from the street would have been a better choice for us.
Be aware the accommodations are in a bustling pedestrian street with lots of tourist and partying. When we were there in late May it was full of 20-30 somethings enjoying the many bars and restaurants and having a lot of fun. Our personal preference would have been for a more subdued residential neighborhood. But if you like to be festive and in an exciting area Travestere is a solid choice.
The only other comment would be about the bath facilities. The homes in Rome are low so modernizing them can be tricky. This apartment relies on a pump for water drainage. It is completely hidden and passive to the guests but does emit and unexpected noise and makes for a slow shower drain. We had to interrupt our showers to allow the shower to drain lest the water overflow onto the bathroom floor. Workable but not ideal.
In summary, Lorenzo is a fine host with a great apartment in a bustling area. If you like nearby festivities and don't take long showers it's a great place to stay.
