Pleasant hotel with good service - average location
Stayed here for four nights whilst at a Downtown convention. Overall a very pleasant hotel, with obliging staff and good facilities. Required extra payment for internet, which is never a plus. A bit outside the core of downtown, but there is a free shuttle bus to get around the downtown area. Good value for money and the valet parking guys were great - very helpful with directions etc.
Rent a car if you go to Houston - the best sights etc. are a fair way out of the Downtown area and having a car makes things much easier.
