Antonio's apartment is the perfect place to stay on Kalymnos. Located just underneath one of the most popular climbing sectors, right next door to the kalymnos diving club and a 5 min walk from the beach, it is a fantastic place to base your holiday from. We landed very late in Kos and arrived in the night and they were very helpful in getting us settles as we arrved. Genuinely one of the best Airbnb experiences that I've had.
It's worth noting if its your first time at Kalymnos, the taxis are very easy around the island and are usually waiting at the ports ready to pick up passengers from the ferries.
Also there are great restaurants right on your doorstep, worth eating out at them as much as you can.
