We found a neglected treasure — a mid-century desert modern former Westward Ho with a Denny’s — dusted it off, gave it some love and made it into Ace Hotel & Swim Club. Our 173-room hotel, spa and resort in Palm Springs, California is within biking distance of downtown and close to cool stuff like Joshua Tree, the Salton Sea, Salvation Mountain, all kinds of historic desert modern architecture and tons of great vintage shopping. It’s also the best place in Palm Springs to get a laid-back massage or natural treatment at the Feel Good Spa, by the pool or in your room.
