I just got back from Italy and spent 4 nights in Praiano at Hotel Margherita at the very end of October. Like many others I had considered staying in Positano and Amalfi as well but finally decided on Praiano.
I had stayed in Praiano last summer at hotel La Perla and had enjoyed it but never really got a sense of the town (or even knew where it was!).
Well this year, at the location where I was staying, I've gotta say I thought it was an amazing town, the Bar del Sole where the locals seem to converge (maybe more touristy in the summer?), overlooking the church where the kids play ball in the evenings while their parents, mostly mothers, look on, the small quiet streets and alleyways, the wonderful people and the great restaurants all combine to make for a great place to stay on the Amalfi coast if you want somewhere quieter than Amalfi or Positano but yet with still a little life going on.
The town is definitely very sprawled out and so may not be for everyone but a lot more hotels offer free parking than in the other two towns (understandable logistically) and many hotels and even restaurants will pick you up/drop you off before or after dinner.
I visited both Amalfi and Positano and both are great places that are absolutely gorgeous, so nothing against them at all and hope to stay in both at some point!
Just a little plug for Praiano as I enjoyed my time there so much!
