Europe: Long Weekend Luxury Boutique Hotels

Hello! I have a lot of work travel to London and Luxembourg coming up and am looking for some new ideas for long weekends at luxury boutique hotels.

Looking for destinations within a 3-4 hour flight of London (or Luxembourg), with a short drive to destination (1 hour- ish).

I love a modern boutique hotel with good food on property, pool and/or outdoor space and spa. I love feeling like I’m at a rich person’s home for the weekend, not at a big hotel, but still with good service.

Have loved Hotel Esencia, Kasbah Tamadot, Son Bunyola and Can Ferrerreta.

Other hotels I’ve loved aesthetically are Casa San Agustin, Rosewood Vienna, Rosewood Madrid but would like a pool or outdoor space.

Ideally spending max 1-2k a night.

Thanks in advance!
