The Black Horse is absolutely lovely. Our room was spacious with comfy a super-king size bed and nice bathroom. It was all super clean. Nice tea and coffee is available to the rooms with fresh milk from the 'coffee station'. Being in a village, it's also quiet at night. One thing to note is that it's road parking as the pub does not have a car park.
All the staff were friendly. The dinner was excellent and we had a lovely breakfast too, with fruit, yoghurt, pastries, full English and vegetarian options too.
Arundel is a short drive away. It's easy to walk to the South Downs for a hike along the ridge.
