Stayed here for a few nights in March 2011. There are two guest houses that are adjacent to each other - the new and the old. The new looks like it's no more than 10 years old. The old one I'd guess is 30 years old but was probably renovated in past 10 years. I was booked into the old guest house. I'd guess the new guest house is somewhat better.
On the positive side it's located right on campus so convenient for visiting/meetings and it overlooks a nice lake which is a main feature of the campus. The rates are very reasonable.
If you are thinking of staying here just be prepared that the guest house is fairly basic accommodation. If you want hotel accommodation then consider one of the hotels located
within a few miles of the campus (which by the way I haven't stayed in but maybe there
are reviews available).
Reception is up a flight of steps from entrance - when I arrived at night to check in the lift was tuned off (or broken?) so I had to lift my suitcase up the stairs. Throughout my stay the reception staff were generally helpful but not especially welcoming. The bedrooms are down a corridor from the reception desk and are basic and reasonably clean, with two single beds, hard pillows and a rather tired looking blanket. There is an old but working window air conditioning unit, and a small flat-screen TV with Indian channels. The curtains look like they need to be cleaned. The bathroom is dark and has an open shower. Throughout my stay there was no hot water. The walls in the room were in need of fresh paint, especially on the walls near light fittings etc. The room has no wireless Internet but does have an Ethernet port. However there is a campus proxy and the reception staff seemed unable to advise on details of address or required passwords.
There is an early morning (630am) knock at the door to offer a cup of tea and a little later to offer to clean your room. If you decline then the room does not get serviced later on that day.
Breakfast is served in a fairly basic dining room (with plastic tables and chairs). For breakfast, the western options are corn flakes or white toast, with (very weak) coffee. There is a toilet adjacent to the kitchen which was a little disconcerting. Outside the meal times there is no food/drink available.
If going back again I'd likely opt for a local hotel, or if being on-campus was important would insist on the new guest house which I'd assume is somewhat letter than the old one.
