I'd like to know of a lodging in Yamashiro Onsen that has rooms with open-air bath and is recommended for couples!

I'd like to stay at Yamashiro Onsen in Kaga Onsenkyo in Ishikawa Prefecture, but are there any recommended hot spring inns that have rooms with open-air baths where couples can enjoy the hot springs together? I'd like to know an inn with a good atmosphere that would be perfect for a hot spring trip with partner.
