This might be my favorite hotel I've ever stayed at. The room wasn't anything special - had a queen bed, a fridge, a small table, and a bathroom that had a shower that spilled everywhere into the bathroom as most did in Greece. The patio was pretty nice when there weren't cars parked on the street (we were on the first level) - you could see the Portara from our room (and the sunset behind it, if we weren't super unlucky with every night we were there being rainy).
But where this hotel really exceeds is the service. First of all, the free breakfast is unmatched by any hotel anywhere. So much fresh food, including quiches, cheese pies, eggs, meat, fresh fruit, bread, desserts, and much more. Everything is fresh from the island and made by the hotel staff. It's a must-have in Naxos, honestly. Apart from breakfast, the hotel staff was awesome, too. They allowed us to check in early, and gave us some house-made wine and quiche upon arrival to welcome us! Due to some miscommunication (that was truly no fault of the hotel staff), we missed out on scheduling the pool & hot tub room a couple nights, and as an apology for the miscommunication (again, not their fault), they gave us a bottle of their incredible house white wine. All of the staff was so friendly and accommodating in any ways they could be. The hotel is also less than 10 minutes walking from the port and bus station. My wife and I would 100% stay here again when we find ourselves in Naxos again someday.
