We stayed two nights at the Marina Riviera. The hotel is just outside Amalfi at 5 min walking distance from the small centre and overlooking the sea. Breakfast is good and you can have it at the terrace with astonishing views of the amalfi cathedral and the sea which improves a lot the experience.
Rooms are ok but without luxuries and are not very big. When we came back from dinner to the hotel one night the lights were out and did not work. No AC either during that night. You can have a balcony but honestly we did not use it much although the views again are awesome. The hotel does not have a swimming pool which might be a disappointment for some people.
Service is nice but nothing special, more like the small familiar hotel type than the five stars hotel.
Overall we were satisfied with the hotel and I think it is a great choice at the Amalfi coast .Amalfi is a great base, the only other option I would consider is Positano, and the Marina Riviera location is perfect so close to the centre and secluded at the same time.
