Thank you Lindsy, it was a pleasure to have you. Being a homeowner is so unpredictable, luckily I just had to press the reset button, and the hot water was back in a few minutes. Living in this home for nine years, that was only our second time having to reset it. Which is pretty awesome. As you can see from other reviews, it has never been an issue. It is a traditional water heater, not a tankless water heater. You may hear us if we are on the second floor because the sleeping area entrance is near the dining area, and underneath the main floor. For example, if we are in the kitchen or dining area for a few minutes you may here us. We are also quiet as possible. However, once we go upstairs to the top floor, you do not hear us because there is floor between us. You also went to sleep early, usually between 8pm-9pm. We usually go upstairs between 11pm-12 midnight. However, we can go up between 9-10pm just let us know. We also have several pictures of the house, so you can see the layout of the house very well, shared areas, and sleeping areas. So there is no surprise, what you see is what you get. Just let us know if you need any accommodations, we want all our guest to have a fantastic experience. Based on your review, you did have a wonderful experience. Thanks again, hope to see you soon.
