We spent here 5D/4N, very happy with the hotel. Definitely will be stay in this hotel again for the next trip.

Good Points :
1. Very strategic location
It is just 3 mins walking distance from Asok BTS, Sukhumvit MRT, and Terminal 21 mall (The newest happening mall in Bangkok).
2. Great room
The room is comfortable, clean, and has 5-star quality.
3. Value for money
It's worth ur money

Downside:
1. Need to have separate floor for smokers.
my room was used by smokers, which it's still bit smelly

2. Breakfast
they always mixed up orders.

The Key Hotel is in a excellent location but prices have been moving up and I expect after the new shopping mall next door is built, it'll cost even more. I paid SGD$65 / USD$55 approx. in Sept 2011

1) Rooms are very small but will have everything you need. Bed is hard.

2) Free Wifi but you'll have to get the password from the counter

3) Food everywhere. There's a foodcourt and macdonalds next door if you're not keen on street food. But Hey you're in Bangkok, there's food everywhere. There is also a small 24 hours mini mart just next to the hotel. Never fear you'll run out of drinks of food.

4) No windows. Instead you get windows facing the corridor. Very odd arrangement.

5) Next to Asok Station.

6) Excellent tailor just across the lane. Look for BOB. I made many shirts with them.

Will definitely stay there again until they charge crazy prices.

In mid-September I stayed overnight in Bangkok at The Key hotel in Sukhumvit Soi 19 on the recommendation of a friend. The Key hotel is in a good location, with only a hundred metre stroll to Robinson Department Store, Asok Skytrain and Sukhumvit MRT Stations. It is handy to the Asoke-Nana nightlife area of this fabulous city. I thought the price for the Deluxe room at 1,700 Baht per night was a bit steep, but a local friend told me the price was about right for Bangkok.
The room itself was immaculate with everything you would expect from a ‘superior’ room including microwave, mini-kitchen, hot water kettle for coffee/tea, large TV, DVD player and a safe. It was quiet and the staff were friendly and helpful.
I may seem very picky but my only complaint was with the complimentary breakfast. The small hotel does not appear to have a dining room so the breakfast is ordered the night before and delivered to your room at an agreed time. This, to me, is not very sociable as I don’t like to dine alone. While travelling, breakfast is always a good time to meet with friends and have a chat over coffee. When the breakfast was delivered I was in shock - scrambled eggs (only one egg used), two small scrawny pieces of bacon, two small pieces of toast and a small glass of juice. That was it. Together, it would have made one not-very-filling sandwich. I have had worse breakfasts, but never ‘less’. I thought at those room prices they could have come up with a better meal.

The Key Bangkok is a great little hotel based very closely to Asok Station / Sukhumvit area. It's very easy to get around Bangkok from, and also has great shops / spa's nearby.

Would definately recommend this hotel to others - me and my friends stayed for a few days before moving onto other parts of Thailand, but liked it so much, we stayed again on the way back to the UK.

Also a good feature they have is that you can book a room just for the day - this is great if you need to stop off in Bangkok for a few hours to rest / shower up before moving onto another location.
