Would choose this place every time!
If you are arriving here via land (bus, taxi, private transfer), this location is beyond convenient - it's right off the main coastal road and not far from a bus station. If you're arriving via ferry, you will have to climb about 10 minutes of steps (or hire a porter to bring your bags up).
The grocery store next door was nice to have and has good hours. They have a little deli in the back and even some basics like shampoo, bug spray, soap, etc. The workers in there are friendly and helpful. So much to do nearby!
Check in was smooth. Margherita [the caretaker] met us there and showed where things were and how to use everything. She gave us tips on how to get around. She is the sweetest! it really felt like you were staying with family.
AC worked well and so did the washer (theres a drying rack). Shower is a little short because of the curved ceiling, but wasn't a problem for me (5'8" 172 cm) - I'd imagine if you were 6'3"/190 cm + you might have to duck a little. Bed was comfortable.
Thank you for a great stay. We would love to stay again when we return to Positano. We had no issues and wish we could have stayed longer!
