HI Melanie, I am very sorry you had a bad experience here. We work really hard at making all our guests feel comfortable, and I am sorry we didn't manage that on this occasion. Regarding your arrival, you came into the house ignoring the 'please ring the bell' sign, and then walked into our kitchen ignoring the 'private' sign on the door, through the kitchen and into our private apartment. I was lying on the couch at the time, which is not the first impression I want to give guests. I have no recollection of 'yelling' at you but merely telling you that you'd entered a private area and asking if you could go back through as I quickly followed you.
Regarding the wifi, we have fibre here and it is very fast. Your husband spoke to Katya who explained this, and that everything was working. Which it was, as she demonstrated. Katya tried to explain to him that it may be his device settings, which happens occasionally. Even so, I reset the router. Everything was working perfectly. We've had no complaints about our wifi. Quite the opposite in fact, so perhaps Katya was right and it was your devices that were the problem.
As for a heated argument between Katya and I, I really have no idea what you are referring to, and can categorically state nothing happened in front of your husband.
Our check out time, as stated in our house rules, is 10am. We simply, and very politely reminded you of this when you did not vacate the room at this time.
As you say, you are in the minority with this terrible review, so perhaps instead of attacking the livelihood of me and my family, which we work very hard for, it may have been better to simply understand that walking all the way through the house, completely ignoring the signs or announcing your presence was perhaps not the right thing to do, accepted that I was caught out and merely asked you to go back, and enjoyed your stay here, rather than taking unnecessary offence, and ruining the experience for both of us.
A B&B or guest house in the UK is not just an accommodation provider, but it our home also, as are almost all rooms listed on Airbnb, and we expect at least a small amount of understanding of this fact and a tiny bit of give and take.
All that said, I am sorry, if not surprised, that you didn't enjoy your stay here. We work very hard, 7 days a week, to ensure people are comfortable here and feel at home, and it is always disappointing to us when we don't achieve this.
