Have used trip advisor to book this hotel for three nights in August based on the good reviews it was given, I can only say that of all the five star hotels i have stayed in throughout the world this is my personal best ,based on value for money, service and facilities.
Our room was on the level eighteen with a balcony, and the view of the sky line was amazing.

This hotel is a must if you are willing to spend a little extra to see how a hotel should be run.

This hotel is fantastic!! We stayed in a balcony room on the eight floor, and loved it.

Definately the best hotel we've ever stayed in (and it's not the first five or six-star, so that is not why). I could go back to Bangkok only to stay at this hotel. The service is what I would call intelligent. Nothing to complain about at all.

Exceeded expectations!

The drive to this hotel and the view up to the hotel is spectacular – the entrance grand and the interior stunning.
Staff go through the motions – they are polite but it’s impersonal with a clinical feel.
It’s corporate with mainly business types. Strict dress code in the bars and restaurants and jeans and flip flops are fround upon.
Pool is great but in parts (there are two sections) it needed cleaning. The view of the river impressive and the staff bring you occasional fruit juice shots which are refreshing!
Good free boat service taking you across the river and various parts of Bangkok.
Rooms are well equipped and the upper floors have great views.
Don’t eat here – it’s over priced and VERY average. I had a tuna salad they used tinned tuna I was lucky to have ¼ of the tin included with the just lettuce leaves. The charge for this was £20.

The Peninsula Bangkok is truly an incredible hotel! My sister and I stayed in a Grand Deluxe room and loved every minute of our stay.

There has been a lot of fretting in previous reviews over the hotel being on the wrong side of the river, but if you are wrestling with that old 'Peninsula vs. Oriental' question, let me put your fears to rest about the Pen being on the Thonburi side of the Mae Chao Praya: it's actually one of the hotel's strengths!

Far from being 'out of the way' and a pain to get to to other side, etc, etc, it is SO refreshing after walking around in crowded, humid, noisy, dirty Bangkok, to step on the hotel's boat and just drift away from it all to the peaceful respite of the Pen. And while I must admit, being a hotel junkie, that I would like to try the Oriental at some point, I can't imagine the view of sleepy Thonburi being much to admire from one's room at night. It's almost like living in Manhattan on the Hudson River. While it's a great location, you're looking out at New Jersey!

But from a room at the Pen, you have floor to ceiling views of the river and and at night, the glorious, twinkling Bangkok skyline. Could anything be better?

The rooms are huge, with a comfy sofa, armchairs and coffee table, and decorated in understated luxury. The elegant, marbled bathrooms boast twin sinks, and are spacious enough for two people to move around in easily.

The lobby level fitness center is airy and equipped with modern machines, and located on the lobby level, which was a big plus for me. The pool is very pretty albeit a bit small, surrounded by canopied, cushioned cabanas. It looks right out onto the river--a relaxing way to end the day!

The food was good, particularly the buffet dinner, which offered an enormous variety of scrumptious, artfully prepared dishes(and I typically abhor buffets). Oh, I forgot about the instant coffee--ugh! But it's not just here--southeast Asians just love their Nescafe!

We always experienced good to excellent service at the Pen, from the men operating the boat, to the smiling assistant managers who brought us our camera that we had forgotten down by the pool. The concierge was a little cool, but that didn't phase us as he was also incredibly busy. Bonus points for the fact that even after we checked out, the bellman stored our hand luggage until after we'd returned from our jaunt down to Phuket.

Another great experience at a Peninsula--I highly recommend it!
