There was nothing we didn't like about our stay at Zefyros, but we would have enjoyed having a fly screen on the terrace doors to help reduce the mosquitoes, though the netting over the bed was a plus. (However, fly screens were not common in the other accommodations along Plaka Beach that we looked at, except those at a higher price point.)
The owners made us feel very welcome, like old friends. They picked us up at the port, made sure we had everything we needed, and were always available (living on site) to provide anything we required that wasn't already in our room. Within an hour or two of our arrival, they arranged for the delivery of two bicycles we could rent during our visit at a very affordable price. Our room was airy, spacious, very clean and comfortable. The terrace was also spacious and aesthetically simple and beautiful. The view is of small farm fields, a few small white-washed buildings, flowers and, in the distance, the sea. (We viewed rooms at 6 other studios/hotels along Plaka Beach, and Zefyros is one of the most aesthetically pleasing, airy and pleasant, and the terraces have some of the most peaceful views.) Although we were a little distance from the beach, we fell asleep to the sound of the waves, which was lovely. (From some of the other hotels/studios nearby that we viewed, which were nearer to the beach, you couldn't hear the sound of the waves at night.) Adonis and Arriane also charmed us with their warmth as well as with small gifts of wine, cheese and fruit from their family's farm. Considering the very affordable price, we felt totally spoiled. Zefyros is located a short walk from the beach. We were there at the end of May/beginning of June, so Plaka Beach was very quiet, even along the beachfront. But within a week (when we came back through Naxos on our way home) the beachfront was very busy, and we know that, any time after the first week of June, Zefyros would be an ideal choice for quiet and peaceful accommodation within walking distance of the beach. We enjoyed the five minutes of cycling, or 8-10 minutes of walking, from Zefyros to the (peaceful end of) Plaka Beach, and to many good restaurants. It was another few minutes cycling to a mini-market.
