After making a last minute booking (in the airport immediately after arriving in Chiangmai), arrived to find the place closed up with no staff working. Someone that was staying there explained that the staff goes home after a certain time, but called the owner for me. She said that there were no rooms available and she had forgotten to block off the dates on the Orbitz system. Luckily the same helpful guest knew of a place nearby that was very professional and accommodating and gave me a room at a similar rate. The owner promised to refund my money by 9am the next morning.
The next day my refund hadn't been processed so I went back to Porwa House in-person. I still needed a place to stay so I thought there must be a way for us to work it out between ourselves. They told me I have to go through Orbitz for the refund, which meant spending MY time to call Orbitz and deal with their customer service people. Then they offered one of the spa massage rooms with no a/c at a rate that was, in my opinion, laughable. This showed me they were not serious about making things right. I also witnessed the staff being very argumentative and defensive with a spa visitor that had made a massage reservation they had forgotten about.
In all this process, I did get a look at a couple of the rooms. They were sparse, but clean. Unfortunately that's about the only good thing I have to say about Porwa House.
