Dear Jiyune, Thank you very much for your message and taking the time to leave us a feedback. In order to preserve the traditional construction of our machiya houses, we install floor heating on the second floor only - but each room on the second floor is equipped with an air conditioner with a heating function and our staff can provide additional portable heaters or humidifier as well. We are happy to hear that you had an enjoyable time and everything went smoothly with the delivery service. It would be a pleasure welcoming you back again! Kind Regards, Machiya Residence Inn Staff
