Because of the location it was a good hotel, but I wouldn't recommend to stay at this hotel.
The staff of the reception wasn't that polite to us. By checkin' in they had no reservation book an couldn't login at there booking.com account. Because of that we couldn't get into our room. After a long time we claimed a room with breakfast (as we booked at booking.om). Our first room had a broken window, and the second room was oke except the cockroch. Because of the service and not well organised reservations I cann't recommend this hotel.
With a stay at Hotel Mega Proklamasi, you'll be centrally located in Jakarta, within a 10-minute drive of Indonesian Ministry of Foreign Affairs and Merdeka Palace. Featured amenities include dry cleaning/laundry services, a 24-hour front desk, and luggage storage. Self parking (subject to charges) is available onsite.
