I stayed in Valentina's apartment for FOUR WEEKS which is probably a new record but I did not regret one day of it. The apartment is in a perfect location in Rome and the neighborhood offers many restaurants, coffee shops, and at least two markets close by where guests can buy some groceries. My Self-Check in was very easy. The place was very clean, the kitchenette allows you to make coffee and some easy dishes, the bed was spacious and comfortable.
Valentina is truly a super host who was always extremely helpful and available. She even had to come to my rescue once when I locked myself out of the apartment, and was nice enough to arrange for an e-bike rental with one of her friends.
In short: whether you will stay a short or long time, you cannot go wrong with Valentina AND her place.
