Go for it !
The apartment is very well located and comfortable, probably suitable for 4-5 persons (we were 3).
Elisabetta is a charming professional guide, who guided us in Pompei, gave us many useful tips for places to visit (including the excellent pizzeria next door) and arranged taxi appointments at fixed price.
In short, everything was smooth and enjoyable.
