We stayed in the Blue Room for 3 nights and loved it for the ambience and decoration, and the view of the river. We used the deck which overhangs the river probably more than we should have, as we should have been out sightseeing.
We ate 3 meals there and really enjoyed the simple food produced. It was tasty and good value for money.
There was one negative for us. The first is that the taxi driver and guide we requested was unreliable and tried to rip us off. He did not turn up the second day, arranging instead for someone else to do it for him. The second driver was much better but had not been given the agreements made with the first one, and although sorted out, left a sour taste and reflected on the hotel as they had arranged it for us.
We loved this hotel because we did not want to run around Bangkok at the end of a long holiday and we enjoyed sitting and soaking up the atmosphere of which there was plenty. I would recommend to those who like boutique and slightly quirky (n a good way) hotels.
