In 2018 we atayed one night in Hotel Gaia in Basel, near the end of our trip. We wanted to be close to the main train station for convenience on arriva from Geneva, and departure to Colmar. This hotel was perfect for the purpose. And today I learned what a caring place it is.
I got an email announcing the departure of two important staff members, one a woman named Selina who was a leading figure in moving the hotel toward a more environmental-friendly approach to lodging. The other is a collie named Aramis, whom we did not have a chance to meet. You can read about them here on the hotel website:

I would recommend this hotel for a stay in Basel in any case, but this email just confirmed that they are a caring company, worthy of support.
We found a lot to like in Basel. It was August when we were there, and my husband joined the river swim, which had lots of people participating. In the morning before catching our train to Colmar, we explored the Old Town, which was beautiful and interesting. There were lots of interesting museums on offer which we did not have time to see. Perhaps next time.
