I stayed at the FS Astor the beginning of November 2022 (in a lead in room mind you), for two nights for about 370 euro ai/i (plus FHR amenities). I thought it was reasonable especially considering most facilities were closed for the season. I did think it was a lovely property, and very interesting with the three distinct hotels within a hotel, we got lucky and had great weather and enjoyed the location outside the madness of the city. The rates I am seeing now are quite absurd though, might as well go stay at Amanzoe.
