Could Have Been 4 Stars
Overall the Hyatt House has a lot to like. The rooms were generally clean, a lot of space and a good value. The TV was new, and the WIFI worked well. I had my kids with me this time and the pool was a nice size, and well maintained. The front desk staff was very friendly and helpful and the woman who handled the free breakfast was very nice and helpful.
The free breakfast was very good and they also had a cocktail hour with free beer both big pluses. 
The location is near the Galleria and also a couple of highway exit ramps so a pretty good spot. Also lots of restaurant choices nearby. 
My only issue was the house keeping. I had two rooms and when I arrived one of my rooms wasn't ready until after 6pm. The manager ended up cleaning that room. Twice the same room wasn't made up. The staff did make amends are were very apologetic about the problem. My guess was that they were having some kind of problem with the staff on my floor, because overall the hotel was spotless and the staff did a good job on the one room they I had that they did clean. 
In conclusion, I do think that my experience was probably just one of those things that happens sometimes and not a major problem with this particular hotel; nonetheless, I did dock the Hyatt House a star because of it for this trip.
