I'm really sorry to hear about your troubles even though I have to say I'm quite not sure to understand what you are talking about. We have had a 5 star review just a few days before your arrival (Wendy 5-11 Oct) and I swear to God there is no mould at all. Additionally, you have stayed 4 nights and never mentioned any issue other than the hot water which has been sorted in no time. The problem was that you had too many showers in a row and the pressure in the boiler went down. We just restarted the boiler, there is no need to give a lot of instructions, it's a simple switch with written RESTART, that's it. Also there is a fan to be switched on in the bathroom to extract the steam after the shower, I'm now thinking that you have not used it at all. In the private feedback you wrote that you because of the smell you were 'Bleeding from the nose and cough'... come on Ville, let's be serious, I understand maybe you are trying to get a discount but this is too much. If this was the case you would have left the apartment the same day of the arrival. Again we have not heard from you at all, normally when guests do that means everything is fine. The travel adaptors unfortunately keep disappearing, however it's a courtesy we are happy to offer but without obligation as specified on the description. The TV works fine but it's not pay tv of course, so you will see regular channels such as BBC, ITV etc. only.
All the apartments are exactly the same size and price, no one 'screwed' you.
We always tell our guests if there is ANY problem please let us know and we will sort it. In this case I have the feeling it's a sloppy attempt to ask for a refund based on nothing. What a shame.
