I agree with the posters who said that guidance on where in Houston the OP wishes to be near would be helpful. I also agree that the Galleria area is a good place to stay if you're looking for the best place in general.
Sadly, I can confirm that the IC Houston has been closed for a while now. I really liked it despite the traffic on I-610 West at times. I've not stayed at the Hotel Indigo Galleria, but I have stayed at the Crowne Plaza on I-10 near the Galleria. I believe it comes up as Crowne Plaza Galleria on a search. It's a decent hotel with typical comfortable CP rooms. I'm always there over Christmas when the lounge is closed, so I can't comment. The hotel has a new feel, is comfortable and clean, and the location is convenient to the major highways in town.
Good luck!
