This hotel was fantastic! Check in was easy with friendly staff, the room was beautiful and well appointed. Breakfast was advertised as a Continental, however they had hot options as well, which was great. Every staff member we saw in the hotel said hi and was friendly. I would definitely stay here again!

The cafe that sold breakfast ran out of healthy options each morning (yogurt parfait cup/ overnight oats & quinoa $8 each) They had other plates, egg with meat, etc that looked nice fwiw. Cute gift shop in the cafe. Fashionable hotel with no real 'front desk' just a checkin counter, but volunteers were staffing a St. Louis info table in the lobby while we were there- very friendly. The bar/tapas restaurant across the lobby was fun, $$, and kitchen closed at 10 or so when our events got out so I didn't get to try it. LOVED the historic building, originally a YMCA, the handsome billiards room and the terrific tiled pool with vaulted ceiling- they don't make them like that anymore. Steam room, sauna, showers were great- bring a room towel in case the spa runs short! Open til 10:30p or 11p fyi. Art Museum on the 2nd floor is free to visitors, and had some challenging, gorgeous, funny, and thought-provoking art. Historic Campbell Mansion next door was a neat contrast and a quick peek into the high Victorian era. Glad I went, would stay again
