An amazing little hotel with very friendly owners/staff. Only six rooms but a decent-sized pool with easily enough sunbeds and umbrellas for all. We used the hotel as a 12-day base for multiple roadtrips to Olympia, Sparta, Mycenae and others, but every other guest only stayed 1 or 2 nights on stopovers.
On our non-travel days, we often had the entire pool area to ourselves, but all was quiet if other guests also used it as everyone wanted to sunbathe/sleep in peace. The rooms are very comfortable with a little kitchen/microwave/kettle for cooking meals and TVs with Amazon, Netflix etc.
There are multiple supermarkets nearby for shopping. Buy cat kibble and make friends with the strays who seem well-looked after by the always-friendly locals.
Nafplio town is very pretty, a 30 min walk from hotel to harbour. LOTS of pretty bars and restaurants, the ones facing the fort in the harbour offer great sunset views. There's a huge free car park if you want to drive. Lots of beaches, our favourite is on other side of the hilltop castle, a 10min drive away. No facilities but lots of space, esp on weekdays. Beaches a bit further away have bars and restaurants.
Thank you for a wonderful holiday!
