We stayed here as part of a tour. It was by far the cleanest of all the places we stayed in on the whole tour, even the more expensive 4 star hotels. There is a huge window from the bar into the kitchen, and the kitchen was just as spotless. The staff are friendly and helpful - it's a family run business, so they know service counts.
The rooms vary in size and views, and many have private terraces. Ours was large, with a terrace, but limited view. The bed was comfy (for Italy where beds are harder than we're used to). The air con worked well (once we realised it would only work if the patio door was closed - a great energy saving feature!).
Free wifi in the room was generally very good, although sometimes a little slow at periods of high demand - we found opening the door to get line of sight to the wifi booster helped.
The food in the restaurant was excellent, much better than the menu outside suggests, and there was a good variety for breakfast.
It is a 3 star hotel, but this is a reflection of the faclities NOT the quality. There is no elevator but the staff will take your luggage to/from your room. The public areas (bar/reception) seemed a little hot at times, but not bad enough to complain.
Massa Lubrense is definitely not as touristy as Sorrento or Amalfi Coast, but it was nice to be somewhere more real. If you don't have a car, there is a regular bus into Sorrento (takes 10 to 15 mins depending on tthe traffic), and ferries/buses/trains from there.
Would highly recommend the hotel, with the understanding that it lacks the famcy features given with a higher number of stars.
