Beautiful apartment in a really central location. The archaeological museum is only 10 minutes walk and the old town is 15 minutes walk. You can also walk to the train station in 30 minutes. There is a metro station 5 minutes from the palace.
We were left lots of tea, coffee and milk. Everything we needed was in the apartment - including towels and shower gel.
The local area is also really beautiful. Lots of small streets to walk around. There is a daily market right outside the palace gates and plenty of local shops.
Our welcome was great, Celesta's mum told gave us maps and recommendations. When we left Celesta's mum looked after our bags for the day - which we were very grateful for.
As the description says, the stairs into the apartment are very steep and small so it is not recommended for people who struggle with steps. The ceiling in the apartment is also quite low so probably not a good place for tall people.
We would love to stay again next time we're in Napoli.
