The hotel is located near the railway station from the airport and also within walking distance to the central area, including Plaza Indonesia and Grand Indonesia.
The hotel staffs were quite helpful, storing my luggage before check-in (6:30 am), giving me an advice on the access to the airport, and so on.
Although the hotels.com notes wifi is available only in the lobby, wifi was also available in the room. The wifi speed was sufficiently fast.
The area is surrounded by lots of street stands and you could easily find places to eat like locals.
