Recently I went to the solitaire resort for approx 2days and it is a 4star resort. To be honest it is one of the best resort in banglore and it is very good for business purposes. The services they offered and from room to banquet, buffets are very nice.
After experiencing it you feel like you are in 4 star hotel. Cleanliness in rooms and toilets which are probably big concern is also maintained nicely. Overall very good resort.
