I am very sorry to hear that you didnt have a perfect time at my house. According to Michael, him and his family did a full house cleaning before you check in (as there were 3 guests coming in on the same day), please tell me which part of the house was dirty and I will make sure they are up standard immediately.
As for the bike rental, I had no idea of it because you dealt it with Michael and you never mentioned to me about it. Also because it was a deal between you and Michael, I am not sure why would you be complaining about it on the review when I have no part in it.
As for the Wifi, I did mention it to you and provided a solution that I will sponsor you half of the cost (or full if you stay over a week) to get a sim card from three which you said you were totally happy with the arrangement.
The sim I suggested you to get would give you 12 GB of data at 4G speed. So I am not sure why would you say it wont last more than 2 days, unless you are using over 6GB per day.
Lastly, I would like to mention that you stayed here for 7 days and you have never mentioned or complained about any of the above problems to me and I rarely get complains about the cleanness of the house(if you look at other guest reviews) so I am a bit confused why wouldnt you tell me earlier as I would definitely look into it myself.
