Anastasia's place is exactly what you need, and where you need it for a trip to Naples. It isn't the biggest place, but it's big enough for two - and if you went to the effort to go to Naples, you're very likely eating outside, so the kitchenette should be enough for coffee etc.
Anastasia is a terrific host - and super helpful.
If you do stay at her place, up the road is a takeaway spaghetti hidey hole called 120 Grammi, very clutch.
