We had an overnight stay here for a last weekend away as a family of 2 and it exceeded our expectations. In a pretty good neighborhood, in good distance to everything around we wanted to do. The amenities were great, we didn’t get to experience the bar by our own choice but it looked fun too! The breakfast options were great and delicious, the waffles were A+.

Like more of the average starred hotels I took with a grain of salt when walking in, it had a modern but pleasing look. Checking in was a little confusing but staff was very helpful. Then when getting in the room it was tad bit smaller than expected, Although beds were comfortable and didnt mind the a/c noise as long as it worked. Plenty of towels were provided I would say I would comeback if I were planning to go to St.louis again
