Fabulous experience at the Glasshouse. Lovely room, wide range of classes and such tasty, nutrtious food. Visited in September for a few days midweek and found a very relaxed, peaceful retreat. It offers a great opportunity to detox if that's what you want, or a luxurious treat to have 3 couse dinners and wine if you don't. The staff are all friendly and helpful and offer taster sessions for things like Tai Chi and Cryotherapy alongside traditional spa treatments. A nice touch was a dining table for solo travellers if you want some company with your meal.

This spa retreat is fully equipped with all needed to rest and rejuvenate in the same location. Everything and everyone was top tier in service and presentation. The only let down was the food and even that was fine it just didn’t match the other areas of excellence
Easy like Sunday morning 🧖🏾‍♀️

Rooms are beautiful and clean. The Staff were amazing, polite, welcoming and attentive, the resort felt like a home away from home. Food was delicious and my spa treatments from Zoe was unbelievable. Zoe made me feel comfortable, relaxed and the whole experience was just amazing. I will definitely be returning

I had a fantastic stay at the Glass House retreat - the team were amazing! Friendly, supportive, and attentive, they made sure I felt right at home. My room was a treat: clean, bright, and airy, with a fabulous rainforest shower and super comfy bed. And wow, the food! Every dish was delicious, I wanted to take the chef home with me! There were loads of activities to keep me busy, and I left feeling refreshed and recharged.
