How to choose a Hotel to stay
In most cases, tourists want that the hotel is not in a remote area, local transport is easily available, Indian Food is available in the vicinity, the nearby area is vibrant and lively, internet accessibility is there etc. Normally, the hotels in the Silom and Sukhumvit areas fit the bill. These are the most "touristy" places, have access to sky trains and underground trains, nights are lively and Indian food is available round the corner.
While in the hotel, avoid eating or drinking from the mini bar as the items may be expensive. Using the hotel phone or internet services will also come heavy on your pocket. In the Silom and Sukhumvit areas, you just have to stroll a little bit here and there to find the items you need at the market price. In most cases the ubiquitous Seven Eleven should be sufficient for your needs.
