Blossom Hotel Houston, Curio Collection by Hilton
The Blossom Hotel is absolutely amazing. The staff was friendly, the room was gorgeous and the lobby is beautiful. Every area of the hotel was clean. The breakfast was delicious. I stayed for one night and hated that my stay couldn’t be longer. I will definitely stay at The Blossom when I am in Houston ...
