My wife and I had a lovely stay at Melrose Sorrento. As others have noted, the property is unconventional, as it is a block of apartments that have been renovated and refurbished into very comfortable and modern hotel rooms. The bed was very comfortable and the highlight was the shower. Nice bathrooms are hard to come by in Italy, and the rain showerhead was great to relax under after a long day. Plus, we never ran out of hot water.
Marialuisa at the front desk always greeted us with a sweet smile. Breakfast was a simple Italian breakfast with your choice of pastry, yogurt, jam/spread, beverage, and the option to add a mixed fruit and meat/cheese plate. Breakfast is served in your room at the time you set, and it's a great way to start your day as you get ready for whatever excursions you have planned.
My one criticism is that on the hotels.com page, it lists laundry service as an amenity. We were arriving in Sorrento after a week and a half in Italy and I was specifically looking for a hotel that would take care of our laundry at this point in our vacation. However when I asked, she said they weren't equipped to do so and pointed us to a laundromat. It was an unexpected inconvenience as I was planning our trip around this laundry service amenity. We had to get up early to do laundry and then head to Positano in the afternoon for just a couple hours when we had planned to spend the day there. It was a disappointment and they should remove the amenity from the page.
