The location is amazing! Short walking distance from St Peter square and Ottaviano metro station. There are two bakeries in <1 min walk for your breakfasts.
Check-in experience was great, we could check-in a bit earlier which is nice!
The apartment itself is nice and matches the advertised pictures. Kitchen is small but very well equipped. Bathrooms are very clean. My only complaint would be that the sofa bed in one of the rooms is not very comfortable (but I suppose that's expected of the sofa beds). The beds in two other rooms were great.
