Here are the three major drawbacks that require improvement:
1. The Wi-fi is not working when we checked-in. We waited 6 hours(from 1:30 PM to 7:30 PM) and the host only claimed that The Wi-fi was working in the past. We showed him the proof, for example, the TV can't connect to Wi-Fi, and our cell phone can't access to internet. But Eric refused to recognize and didn't solve the issue for 24 hours. We have to book another hotel for our stay.
2. The air conditioner inside the room took too long to respond. It took the air-conditioner 2 mins to respond to temperature change. This garage is so close to the house and utility room in the garden such that I could hear people talking when they fetch items from the utility room, which is only one wall away from this garage. This air-conditioner ( I guess the air con is a model in 2000s) really needs to be replaced. The refrigerator is also a very old model, but it can still work - the air conditioner is really something that needs to be replaced soon.
3. When you take the shower, you would need to wait for 5 mins for the hot water in the rest room. After you take shower for 10mins, there is no more hot water again - and you would wait for another 5 mins for the hot water to come back.
4. Eric never replied to my message in a timely manner, including Wi-Fi issue, access issue, hot water...etc.
He claimed that he should refund me some amount, and I waited for two days, sent him the request. But he refused to respond.
5. In a nutshell, this garage is absolutely the worst place I have ever stayed, in terms of Wi-fi, hot shower, air-con, noise control... I hope future travelers, especially international traveler, could have a better experience.
