This is a fantastic place to stay. Great location near Vatican City, and it's a quick walk to metro station to get anywhere in and around Rome. Location is also across the street from a market and very close to regular supermarkets. There's a great place to get wine across the street as well (he will not steer you wrong with suggestions and is very nice).
Plenty of space. Good bathroom. Comfortable bed. We were able to use the washer/dryer. NOTE: Take your shoes off when you enter the apartment.
Natalia and her family were great. Great hospitality. Natalia always offered fruit, snacks, coffee, etc. One night we had an impromptu dinner with the family and it was a highlight of our trip. The food was delicious and the company was even better. One of the best things about travel is the people you meet and spend time with. We would gladly stay here again and strongly encourage others to do so.
