I happened to stay in Ginger Mysore in Oct11. Heres my feedback on the hotel based on the stay:
+ves:
Location: In the city center. It is right near the tourist spots like the Mysore Zoo, Mysore Palace etc.
Cleanliness: Pretty well kept and clean
-ves:
Congestion: The rooms are too congested. Even double rooms have no space other than the space for cot. Especially if you have a kid, you will start feeling claustrophobia
Parking: They dont have parking spaces for all the visitors on any given day. Unless you reach earlier in the day, you might end up needing to park outside the hotel compound.
So, if you are a solo traveller or a business traveller for a quick trip to Mysore, this can be a very good place to stay. If you happen to be here with family, you might feel like getting inside the room only when you are just about to sleep. Folks who have not experienced claustrohobia can experience it here.
