I stayed in Jakarta twice in the last few months, once at the Le Meridien, then at the Oakwood Premier Cozmo and what a difference. Oakwood apartments are huge, modern and well fit out with a kitchen, laundry facilities and very comfortable bed and furnishings. The room service food was great, and there is a Starbucks and a supermarket on the ground floor. Transport in and out is much easier than the other 5 star hotels as they are on a large road. Traffic is a big consideration in Jakarta, here is some other advice to help:
1. When u land and want visa on arrival, you can pay 250000 rupiah, Or US$25 to get it, you will need to arrive with cash, no ATM when u land
2. When u depart it is US$15 tax to be paid at the check in counter
3. Check in counters are past security not before like every other airport
4. Taxis can be unsafe, only book Silver Bird or if on a budget Blue Bird, but those drivers don't have great English so take instructions in Indonesian
5. Traffic in Jakarta is awful, worstnin the world that I have experienced and I go to India often. You will travel on average 8km an hour in peak time (7-10 and 4-8) but don't be tempted to walk, it isn't safe, so just try to arrive or depart outside those times.
6. Last advise is definitely choose the Oakwood Premier Cozmo, it really is an oasis in the city. Not only are the rooms and surrounding facilities fabulous, it also had a lovely pool to relax at should u get good weather!

Happy travels!

Located in the relatively quiet Mega Kuningan area of Jakarta, staying at the Oakwood has been a very pleasant home-from-home experience. The rooms are spacious, clean and homely... fully loaded with everything you might need. The staff are friendly and very helpful - clearly well managed with customer satisfaction in mind... wonderful.

Loved staying in this place, it was very spacious, clean and convenient. It had all the convenience of a hotel such as room service, but with lots of room to move about and not feel as if you are in a box. I stayed in a one bedroom apartment and it had a guest room. Great place and i would stay here again.

When you arrive to Jakarta for the first time, my experience is that it can be quite overwhelming. It is therefore very nice to have a place like Oakwood where you can settle. Very spacious apartments, with friendly staff, and a tasty foodcourt. Taxi services into town in front of the hotel.

Only comment is that for this price you would expect wireless internet to be included, but it was not.
