Took my partner to stay for her birthday as part of a couple of days in Rye.
The rooms were a decent size and the bed was much softer than I'm used to but really comfortable, there was a small but very modern bathroom with an decent sized bath which my partner appreciated. I imagine Oast Houses are listed, so while there was a worry about it getting too hot at night due to no air con, the room was airy and comfortable, the even supply a large fan should you need it.
The building itself is magnificent, one of the few Oast Houses open to the public, was great to see part of the Kent/Sussex heritage close up.
The food for both dinner and breakfast was great, good options for vegi/pescatarians, the service at dinner was great given it was the manager and the kitchen staff only, and it has an open to the public bar, and she was also checking in guests, and the food was delicious. Likewise the breakfast was high quality and quick service, very pleased with it. The bar is small but has plenty of options including local ales and there's a great little garden to sit in and watch the house martins dashing about in the evening sun.
It's located a mile out of central Rye, so it's very handy for town (up a hill all the way from the centre, it's paved though) and the hotel supply a load of taxi companies in case you don't want to tackle the hills or are going further afield.
Overall, a place unique to the region and having a cozy, welcoming feel to it with good food. Recommended.
