Thought I would give an alternative view to ones that seem to be on the web. We stay at Hotel Elizabeth everytime we are in Bangkok. We like the location as we visit Chatachuk market and the hotel is very close to the sky train and subway stations. We find the help VERY friendly and polite. They remember us each time we arrive. The room is more than adequate for people who are looking for a room at a great rate. The breakfast is a fantastic Thai breakfast. This is truly a Thai hotel that is not catering to foreigners. If you're looking for a Thai experience you'll get it here. If you want western standards, you'll have to go elsewhere.

In 2003 we stayed at this hotel already. It was worth the 900 baht.
On 10th of August 2005 we reserved rooms there, personally, directly at the counter, for August 31st to September 6th. They told us: 900 baht.
As we arrived, suddenly the price was 1300 baht for farang, 900 baht for Thai only. And, also suddenly, the desk personal understood no more english.
We saw no other chance to stay one night.
Recognizing the dirt and the moldy shower curtain, I must say that it is even no more worth 900 baht.
Moreover, the "farang" component of the breakfast is way too poor for this price.
We found another hotel in the near and moved out the first morning.
