Spent 2 nights at this apartment with my husband and two daughters and found it exactly as described. We did not meet Celesta but we were well looked after by her mother Mena. We arrived much earlier than she expected but she happily welcomed us in and made us feel comfortable whilst she finished off preparing the beds. The apartment was spotlessly clean and had everything we needed for our stay. Mena showed us around, connected us to wifi and recommended a good local pizza place. She was very apologetic about her standard of English but I thought it was fantastic and much better than my Italian. The apartment is in an amazing building and is worthy of a visit regardless of if you are staying there. the neighbourhood is busy and lively, we always felt very comfortable and safe in the streets around. It is very close to the centre of Naples and we were easily able to walk to the cathedral and lots of other historical sites. The metro is literally around the corner and is only one stop to the main train station.
The apartment itself only has one window in the main room which opens into a small inner space which meant it was very quiet with no street noise but also meant there wasn't much airflow. Unfortunately for us it was very hot during our two days and although the apartment had a lovely big fan there is no air conditioning so we found it difficult to sleep. that being said, we would definitely choose to stay here again if celesta and mena will have us !
