Top O'Fallon Hotel Reviews

Pear Tree Inn St. Louis Near Union Station

10/10 Excellent

"The staff was extremely helpful"

Moonrise Hotel

8/10 Good

"The hotel is beautiful, the beds and pillows are super comfortable, the rainfall shower head is magnificent and the parking is free. The rooftop terrace is outstanding with excellent music and the breakfast at the restaurant inside is excellent. However, it’s cashless. The restaurant isn’t, but I somehow ended up with charges to my credit card from there and the hotel that were unauthorized. My other half made the mistake of going downstairs for a smoke and grabbed a soda on his way back in. He gave the guy at the front desk cash, which he accepted, and was told nothing else. Another time a woman “gave” him two drinks and told him “not to worry about it” when he offered her cash. The other guy took it why would he think any differently. I didn’t know anything until I saw the charges on my card. Why accept the money and charge my room? Why let him take the drinks and say “don’t worry about it” only to charge my room? Why not simply state “we’re cashless?” Won’t be staying here again or recommending this place to anybody because of dishonest employees. It’s terrible because I stay in A LOT of hotels and I LOVED everything else."

Drury Plaza Hotel St. Louis Union Station

8/10 Good

"The room was comfortable. I wish there had been an exhaust fan in the bathroom. It was very humid after showers. The staff was friendly. Breakfast was very good, with many options both hot and cold. Parking was right behind the hotel, however I don't like having to pay the hotel to park in their parking garage. Overall, we had a nice stay."
