Room it self was nice: very clean, modern, ok wifi, good bathroom and big comfy bed (ask more pillows!) Mind though that some rooms are located on the street side and noise from there is quite a bit if you are lite sleeper.
Rooms are located right next to Ottaviano metro station and tram stop. Area has some nice restaurants, not mayby as much as some other areas but we enjoyed our stay. Only thing for staying bit longer here is that breakfest gets really boring as there is no variation from day to day.
Note that reseption is not 24/7 at Rooms, so if you have plans for very late check in, do set it up in advance.
