We stayed 7 nights in Elena’s apartment to visit Napoli as tourists.
Location is great, right in the middle of the old city center, very convenient for all the tourist sites in this part of the city. There are food shops and a supermarket in close vicinity, and of course plenty of cafés and restaurants. Metro and bus station to reach the other parts of the city are never more than 10 to 15 mn away. There is a taxi stand 200 m away.
The apartment is spacious, exactly as described and the photographs provide a realistic description. There is a lift (you need a provision of 5 cents coins as a coin is required for each ride). There is AC in all rooms. We lived there as a party of 2, you might find it is a little under-equipped to cook at home if you come here as a party of 4 or 6.
Both bedrooms look over a narrow street and are reasonably quiet (no noisy restaurants, just passers-by shouting loudly in the middle of the night).
Communication was great, check-in and check-out were very fluid, and the host very kindly let us check-out late the last day (but there are many luggage storage options in the surroundings in case this would not be possible).
