Nice hotel. We booked this using Booking that transferred us to Expedia. In that transfer, dark magic seemed to happen and our dates were shifted out by a month, but the Manager was very good about it, and said "No problem, we have space you can stay". There was some grief with Expedia. Do not bother calling their call center, it is in a machinery repair depot somewhere in India where it is too loud to use telephones. Email them. They were very good about shifting dates and paying our penalty (same as room charge) to the Chiang Mai Gate Hotel promptly.
The hotel itself had a nice lobby, clean, classic look. Easy two minute walk to the actual south gate of the city. Friendly staff who were very helpful. Room was classic, clean, compact but nicely finished. Had a lot of carved woodwork. No view from the room. Shower, no tub. We were located in a wing adjacent to the hotel. King sized bed, no smoking room, fresh sheets, very nicely turned out.
One unfortunate experience - we went to TWO massage shops across the street. Of twenty five massages in Thailand, the worst - by far - happened in those two shops. Avoid them. We needed two massage girls. In both cases one called her untrained friend and talked her - in Thai - through the massage. One, while texting on her cell phone while my buddy was face down. This isn't the hotel of course - just across the street.
Great experience with the hotel, and nearby convenience store.
