I have stayed here a couple of times. My impression has been very favourable.
The rooms are not only comfortable but spacious. The hotel is located in some kind of a shopping centre in one corner. So, it is generally quiet even when the roads outside are busy.
The staff is courteous and the service is good.
The food in the restaurant is decent but the quality varies (probably changes with the chef). You can find the same dish cooked in different ways on different occasions. However, I think the food is much too expensive for the taste and quality. Even good restaurants in Bombay dont charge one that much for the same dish with better quality.
But, overall Galaxy will offer you a nice, comfortably stay. I would definitely recommend this hotel for families and couples who are visiting Jalna.
