We will do everything we can to help you stay at Marina House, however we only feel it fair to mention that Marina House is situated at 200m down a pedestrian only soi. Once you are at the bottom of the soi there are 2 steps into the garden then 2 further steps into the house itself. If you can take a 1st floor room then that will be all the steps you will ever need to worry about.
Marina House regrettably is not suitable for wheelchair users. To be entirely honest, nor is much of Thailand unfortunately.
