This B&B is located in a normal residential apartment block over several floors. I was on level 4 and the room was nice and spacious and clean. It will need a paint job soon but it was fine. The staff are nice and friendly but with limited English. The supervisor speaks English, so if you need anything beyond the basics, contact him.
The breakfast is adequate - nothing amazing, but nice and basic.
It is near two big shopping malls, with a fairly new one being only about a ten minute walk away.
The area seems to be a fairly nice area and as such, it is quiet and appears very safe. However like most of Chennai the main roads nearby are crowded and busy.
My only gripe with this place is that the there is no signage outside, due to the building being a private residential block. I booked through Hotels.com and the confirmation sheet only had the street name and as such, it took the taxi and me quite a while to find the place plus a couple of phone calls to the B&B. I even asked locals and they didn't seem to know of it either.
If you are coming here, look for the Tangy Apartment block - its opposite a girls school.
