4 nights in bangkok was more than enough. But i must say 5 mornings of enjoying buffet breaky here never seemed to disapoint!
Rooms are a lil out dated but for wat u pay, cant really complain!
Had a very disapointing experience with a bell man 'prisit' his name was... Be aware!!! He conned us into using his brother to do floating markets and river kwai tour... All for 3000baht! Bargin as most places u pay that per person! Took a 2 hr drive to the middle of no where turned up at some type of floating market place. With no water insite... We were informed to go on boat it was 3000baht each??? We then worked out what had happened, mr dodgy bell man lied and it was 3000baht for the taxi... With limited english we demanded the driver take us back to the hotel! So all up if we had of been stupid an went along the day would have cost us well over 15,000baht for both tours! Be very careful and book thru hotel directly or registered tour agent! Big mistake!!! Funny he avoided us the rest of our stay!

This is the best hotel I have every stayed in.

Pros:
1- Nice wide clean rooms with wonderful view.
2- Breakfast is amazing, all cuisines are available, varieties of everything you can imagine, plus the view.
3- There is a revolving restaurant with very good prices, very good open buffet, with amazing view in the 88th floor.
4- There is a free revolving roof deck on the 84th floor, where you can enjoy viewing the city from the sky.
5- They have organized elevators based on your room zone.
6- Only 8 mins walk to the metro station.
7- A lot of flea markets and major shopping malls like "Platinum" and "Pantip Plaza IT Mall" are around the hotel.
8- They provide a free shuttle bus to some touristic attractions like Siam Center.

Cons: Wireless Internet is charged.

We stayed here in early November for 2 nights in a deluxe sky zone room I think - we paid extra to be up higher (64th floor). First timers to Thailand and Bangkok.

Positives: amazing views from our room, and from the eateries and bars and lookout on floors 77-83!!
Amazing buffet breakfast selection! Truly international and a great introduction to different types of Asian food not seen in Australian hotels. Same comment for the seafood buffet on Saturday night - and guest pay 50% less than non guests.
Huge staff to guest ratio... Very attentive at the lifts and in eateries/bars.
Convenience store in the lobby open 24 hours - great for water purchases before you head out for the day.
2 free cold bottles of water in the fridge each day and and English copy of The Bangkok Times - both great for acclimatizing.
Nice room with great air conditioning and awesome shower pressure (although the temperature would chop and change a bit
Lobby had separate desks for checking in and out - check out was very quick! (see below for check in)
Across the road from the wholesale market building - very cheap shopping!!
155 metres from train station.

Not so positives:
This hotel has 83 floors- expect to wait for lifts. If you're not great in the heat, take cold water with you. The hallways and lifts do NOT have great air conditioning.
As well as a hotel, this place is a tourist attraction because of its height - so there are coach loads that come for the views! Again - long waits for lifts.
200 bht for 1 hour of Internet access or 400 for the day. Crazy when you can buy a prepaid sim at the airport and have unlimited Internet access for a month for 849 baht!
Public areas of the hotel (especially restaurants, bars) we found very outdated. We felt like we were back in the 80s.
Delays checking in (and that was at 8.30pm)

We stayed 2 time in baiyoke sky. 1 impression was better, now swimming pool is out of order, green dirty watet. Rooms are also not renovated and not very clean if you want to have wide windows on upper floor you need to update your room for 1000bath per night. We nooked space zone, 66 floor. It is nice. The best side is west, from upper floor you will see best part of bangkok. Defenaty have a dinner at roof. They have open terrace as well. Down in the streets if you go left, choose massage salon, second one, then ask Nick, the best massage girl I ever had. Prices for oil massage is 500bath there, later in hua hin we had it for 300. Restairants in baiyoke are good and cheap. Visit fruit corner at 18 floor. It is nice big variety. I like that hotel. Aftet a long flight it is good and within short dustance from the airport. Recommended. Only lifts are terrible, be patient... Takes time to go out or upper floor, till half a hour :)
