We stayed for 8 nights as a party of 4 in this apartment from end December 2019 to early January 2020.
The location is great for tourism, many places of interest are within 30 mn walking distance and connections to public transport are very close and abundant. For food there are many small supermarkets in the area and of course the (expensive) Campo dei Fiori daily open air market - not to mention the many restaurants and cafés. Of course there is a flip side to these advantages: "artificial" shops dedicated to tourism, flows of tourists, street singers in the evening (whom you hear because the windows are not quite sound proof).
The apartment is quite as described. As mentioned by previous guests, be prepared to climb 4 stair levels to access it. It is a "real" private apartment , it has a personal touch that we particularly appreciated because it made us feel at a friend's home. The lay out is great, there are 2 open air terraces that for sure must be very pleasant in summer. The sofas are comfortable. The kitchen is well equipped, even if the appliances are starting to be a little out of date. Wifi, hot water, heating were functioning well. For those visiting in summer, please note that only one of the 2 bedrooms is equipped with air conditioning and that the flat is just under the roof of the building. Each bedroom has its separate bathroom.
The rentals are managed by a professional travel agency. The contacts were both very friendly and efficient. The person who showed us the apartment very kindly gave us all the necessary practical and touristic information. Check-out was very easy.
