In general, we liked the stay in the appertas. Flexible, fast and easy check-in and check-out. Excellent location: the Vatican and the center of Rome are within walking distance, there are many restaurants, coffee shops and pizzerias around, a supermarket is nearby. Accommodation prices are quite reasonable.
As disadvantages, I would like to note the following: one set of keys for 6 guests is very inconvenient, the stove in the kitchen does not function correctly, an electric kettle would be a useful piece of equipment.
Overall, I would recommend these apartments
