Hotel was clean but honestly, outdated. Staff was great. The continental breakfast was fine. Biggest issue was the shower. There was next to no water pressure no matter the time of day. The mattress also felt cheap. I’m not a picky person and overall, I would stay again. Just maybe not in an upgraded room. I don’t feel like it was worth it.

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
