No lunch or dinner onsite only found out when I checked in so did not eat anything for a whole 24 hours. The rooms had nothing in the fridge. No tea or milk so was disappointed

I recently stayed one night at Tetra Retreat and had a wonderful experience. The hotel is newly opened and everything was impeccably clean. My room was very spacious, with two twin beds and a private pool at the back, which made for a relaxing stay. The beds were comfortable, and the water pressure and temperature in the shower were perfect. I also enjoyed an excellent massage during my visit. As the hotel is still new, the sauna and steam room were not yet ready for guests. My only suggestion would be to add another garbage bin near the bathroom sink area, as there was only one in the toilet section. Overall, I had a great stay and would definitely return. I look forward to seeing the hotel once all the facilities are fully operational.
