Of all things, my gripes were about the bathtub.
The tub is narrow, with the curves of the tub walls at the bottom extending into the bottom of the tub, which left almost no room to stand without my adult-sized feet being angled onto the curves at the bottom of the tub. In order to stand flat-footed on the 'floor' of the tub, I had to have one foot in front of the other, which doesn't provide the most stable standing position.
Another gripe is that the floor of the tub didn't provide a whole lot of traction, and I couldn't find a vinyl or rubber safety bath mat anywhere in the bathroom to put in the tub. The minimal traction wouldn't have been so much of an issue had the tub been wider as I might have been able to stand more securely. As it went, the inclusion of the safety bars in the tub were appreciated greatly.
Yet another gripe is that the shower curtain is too short. Twice, while showering, the curtain got pushed to the outside of the tub, which left me with the job mopping up the water on the bathroom floor, using the now sopping wet cloth bath mat I put on the floor. Had the shower curtain been 3 - 4" taller, I think it would have stayed inside the tub.
Other than those gripes, I would stay here again. The room was spacious, the bed was very comfortable, and, other than the street racing that was going on Friday and Saturday night out on Plank road, it was a quiet room. As mentioned above, I will stay at the Hampton Inn Altoona again when next I visit Altoona.
