I wouldn't change a thing
The stay was excellent I would rate this at the top of a home based stay (it isn't a 5 star hotel, of course). Rooms were clean, hot and cold water for showers and private bathroom. Meals were home cooked and very accomodating of dietary needs (unless you need meat). Phone use was available at a billed basis, but just normal charges (not an inflated tourist price).
Sumathi also provided great support trying to help arrange trips and small excursions throughout the city, which was greatly appreciated. Safe area, close to MG road and the airport.
Construction noise is there, but didn't bother me as I was up by that time. I really can't think of anything that I would change to make the place any better.
