The hotel is yes close from the airport, has a free shuttle bus (and on-time!!!)
Price is affordable and clean, breakfast was good
If you are in Jakarta for a few days or wanna rest during your transit, your first day you should stay here!!!
Especially if your flight is after 16:00 or somewhere around there, in this city the traffic jam is crazy, takes literally hours to go to the centre of Jakarta, so definitely you should stay near the airport, go out the next day
