Overall, stay at Dimora was very pleasant. Rooms are outdated but clean, views are incredible, breakfast is light but included. And staff was wonderful.
One thing the hotel should advise more clearly: you HAVE to use porter service from port if you're coming in on ferry. Don't let the "8 minute" walk on Google maps fool you. This doesn't consider the 500 stair steps (not an exaggeration) and verticality of Positano. It was more like 45 minutes with luggage.
But 100% recommend this hotel.
General note about Positano, you have to be OK with stairs. If the average stair case for one floor is 15-20 steps, you can do the math:
150 steps from street entrance to hotel that cannot be avoided.
~250 steps from sea level at port and 1.4 mile walk to get to hotel.
~200 steps from the hotel down to the beach
This is true for anywhere you stay in Positano. But it is a shock. Know this going into it and plan accordingly: porters, sneakers, healthy knees.
