Villa is exactly as pictured. It worked well for our family of eight adults. The town is very friendly and charming, the beach is lovely. It is a pebble beach, and we did use our water shoes, but the upside is no sand stuck to everything! The walk to the beach is a workout due to the many steps, but the water is so clear and refreshing it is well worth it. We ate at La Tonarella and Zeffiro Sereno at the beach and both were good. Rented chaise lounges and umbrellas for somewhere around 10 Euro per person. In Conca we ate twice at La Piazza da Nino where they made an excellent pizza, and once at Le Bonta del Capo, which had lovely views and pretty good food. The little market had everything we needed. We only ate breakfast at the villa.
The villa was clean, beds were ok, could use a few extra pillows, the a/c in the bedrooms was great. As another reviewer suggested, pay for extra towels and floor mats for the shower. I washed the beach towels midweek, but the washer is very slow (2 hours), and there is no dryer, so they had to air dry outside. No big deal, but I should have paid extra for more towels.
We rented two cars, and Cristina provided a parking pass for one. Be advised that the metered parking nearby worked out fine, and you can pay 8 Euro for the whole day. We didn't know that, and started paying by the hour with whatever coins we had, which is more expensive overall.
The villa is located well for trips into the nearby towns. In the summer, Positano, Amalfi and Capri are overwhelmingly crowded during the day (much nicer at night, no night ferry from Capri) and returning to Conca was a welcome respite! We have been to Ravello on two separate visits to the Amalfi Coast and it is much quieter and very beautiful.
On our last visit, we stayed in Praiano, and preferred Conca dei Marini.
I wouldn't hesitate to stay in Conca dei Marini again!
