This is a good choice for families or individuals who need a full refrigerator and cooking capabilities. There is a restaurant across the highway if walkable cooked food is desired. The refrigerator takes 24 hours to get things really cooled down. If you want cold drinks before 24 hours, purchase ice. Also be careful about the temperature setting in the refrigerator. If you put it to max cool (level 7), I recommend turning it down to level 5 after twelve hours. The hotel is quiet and safe. There is plenty of parking. This property was constructed before ADA requirements took effect. There is a wheelchair ramp to the main office, but every room requires at least a few stairs. The breakfast is also up a flight of stairs. If you are wheelchair bound, this is not a recommended option. The staff was excellent. The manager gave us the three additional bath towels we requested without any fuss. The housekeeper will only put back four sets of towels even if you turn in more than four. If you want extra, you may have to ask each day, and the manager will be happy to give them to you. The manager cares about his job and wants to take care of the guests. When the refrigerator seemed to not work at first, he asked me each day afterward if it was cooling properly. Wi-Fi is fast and stable. There is a nice TV, but I did not use it. There is a dining table with chairs and a couch. I will stay again if in the area.
