Amazing place in Ayutthaya. The property is right on the riverfront and seems to be run by an elderly couple. They greeted us very friendly when we arrived with our rental car, showed us a place to park and then sat us down with a refreshing iced tea for the check-in formalities. We were showed to the big room overlooking the river, which had great A/C (it was a very hot day...), amazing views, a comfy bed and was very clean. What makes this place so special though, is the charming furniture / design and the beautiful garden. There are so many great places to sit at the river - whether it's on a swing or on a reclining chair - you don't even have time to see the ruins anymore because all you wanna do is chill in the garden.
Another huge plus was the breakfast. They take your individual order and then serve you tea, coffee, juice, eggs, sausage, fruit, rice thingys, etc. on the riverfront. Simply great! Thank you so much!
Ayutthaya itself was not as cool as Sukhothai, in our opinion, but we would probably come back one day simply for the accommodation ;-)
