Unfortunately our stay at Dan's was overshadowed by persistent problems with the hot water when trying to shower. The water would fluctuate wildly in temperature, often suddenly turning from warm to freezing for several minutes. On one day we couldn't get hot water at all to shower. There were three of us, who all had the same experience, from day one until departure. To his credit, Dan tried valiantly to find a fix for us, even bringing in a worker to inspect the hot water. But despite this, we continued to have the same problem for over four days before reluctantly checking out early and moving to a hotel.
I understand Dan had never had a complaint about the hot water before. I'm not sure if it's a new issue with the water heater, or as Dan suggested to us it may be the building's plumbing is less reliable for hot water of a morning (we often showered around 8am), when previous guests may have showered later, outside peak periods. Though we also had problems trying to shower at 9pm one evening to avoid that peak.
I've never had to make such a complaint before but AirBnB were excellent in handling it and arranging a refund for the remainder of our booking. Dan also gave us a discount for the inconvenience on the nights we stayed.
I should also say that outside our showering problems, Dan's apartment was ideal. The location is excellent, the furnishings comfy, and Dan himself a courteous host who handled my growing frustration with aplomb. The wifi was also very good - we streamed Netflix without a worry on my iPad. Hopefully the hot water issue can be sorted as it was the one blight on our stay.
