We stayed here only as we had the choice of either spending a lof of money for only a few hours, stay in the airport terminal or stay at a hotel (Sun-n-Sheel) for a decent price and have the chance to catch some hours sleep before our flight back to Europe.
The booking included a free shuttle service from and to the airport. Which indeed was offered, in a VERY old car with a driver that seemed to take friends he knew along as well. And when droping us off at the airport even complained about the amount of tip we gave him, as he considered to to be too little.
The room was OK in size but missed quality. The bedlinen seemed not to be 100% clean and was slightly torn. Also did we have to ask for additional towels as only one (1) for two people was provided (usually you end up having at least 4, 2 for showering and 2 for hand washing, tooth brushing, whatever..).
The bed was very hard, just like sleeping on a wooden bord and the noise from the streed was almost unbarable. we ended up having roughly 2 hours sleep. probably the same amount as we would have had for free at the airport.
Also when asking for when to check-out to be in time for the flight we were advised that we needed to be at the airport 3 hours prior to departure, and that we should leave at 1:30 am to be there in time. We ended up being at the airport WAY too early with WAY too much time to pass before departure.
Unless you really need to spend a night in an airport hotel in Mumbai and you really can not afford any other hotel that's on the marked, you can give it a shot. However, next time, I would rather spent some more money and make sure the hotel is a decent one, or just forget about it and stay at the Airport instead. There are several ways to pass time there!
