“What a stunningly hospitable cottage, we loved every minute. It really felt like a home away from home. Spa facilities are amazing and we all utilised the gym, pool, steam room and sauna each morning as part of our ‘routine’! We also had a fantastic evening with our private chef. We can’t wait to come back!”

Good to know

Is the spa really included?

Yes. Two spa passes in the cottage cover your whole group for the pools, saunas, steam room and gym. Friday to Sunday and high-season sessions are booked online from 10.30am the day before; other times are walk-in. Massages, facials and other treatments cost extra, so book early.

What are check-in and check-out times?

Check-in is at 4pm and check-out at 10.30am. The spa and estate facilities are yours from 2pm on arrival day until 12pm on your last day. Whenever we can, we'll happily offer an earlier check-in or later check-out.

Is there a minimum stay?

Yes, the minimum stay is two nights.

What's provided?

Beds made up and towels ready, logs for the fire and charcoal for the BBQ, toiletries, and a welcome selection of Cotswold food and drink. Bring swimming towels or hire them at the spa.

Can we book for a hen or stag party?

Sorry, no. Lower Mill is a family nature reserve, so hen and stag parties aren't permitted.

Is parking included?

Yes, free parking with the cottage's own space, plus EV chargers a short walk away.

Can we bring our dog?

Sorry, no. Cornerstone Cottage doesn't accept pets.
