Newly renovated rooms in Saitama. The rooms are large as they are essentially Japanese apartments which come with washing machine, fridge, sink, stove, tv, heating/cooling. All the appliances are new. Great if you desire a lot of space. Rooms are all non smoking, which is a great plus for my family. Stayed as a family (3 total persons). Easy hotel to find, Warabi station east exit.
The main drawback is the location, it is relatively far from the core (35ish minutes to Tokyo station, 40ish minutes to Shinjuku). They don't clean your rooms everyday either, only once per stay, but was not a problem for me.
Would recommend if you are not pressed for time. Good if you want to experience regular suburban Japanese life. There is a relatively large mall nearby (Aeon mall) as well.
