Best location for conventions
I stayed at Hilton Americas in Houston this past May when i was there for an international conference. The facility was wonderful, and the staff was well-trained and helpful. What I enjoyed most was the location, because I could get easy access to the convention building through the skywalk instead of walking in the heat in my high heels. There are several nice hotels within a few blocks from the convention center; however, considering the extremely cool air in the conference hall and the heat outdoor, even one block makes a different! The hotel is also steps away from the Green and the lake park (a very cute but small park), and it is two blocks away from the grocery store and a few blocks from the Tunnel (lots of shops and dinning underground). Downtown Houston has many luxury hotels, but I saw many homeless people wandering around in downtown. I consider Hilton America a nicer and safer location.
There are fine dining and bars on site as well, which provides more options and convenience to the guests. The gym has a great sky view, and the swimming pool is on top floor. 
There was only one disappointment. My former colleague dropped me a gift bag at the concierge. I forgot to pick it up that day, and it was lost when I went to pick my bag the following morning. Although the concierge patiently helped me to search for the bag and followed up by phone calls, I didn’t receive my bag at the end. 
Overall, I enjoyed the location, the welcoming staff, and the comfortable bed. Hilton Americas is an ideal for business/conference travelers who need to spend a lot of time at the Convention Center.
