Double room - long or short stay

Mahsa stayed 14 nights in a huge elegant room in a beautiful unique 1860 town house and yet choses to use the review process to cause offence and mislead. She has recourse to Homestay or myself if it was terrible and could stay elsewhere if complaints are upheld. It is to be noted that we have regular guests via other websites who are aware of what a homeshare means. We have had guests all year round since the inception in 2016 most are lovely and stay long term. Firstly our 4 bathrooms are shared. Mahsa chose to use 1 where unfortunately she found it unflushed on one occasion. She admits that she was only sharing with 1 other person and could have had a quiet word. She simply flushed it and I stepped up my patrols of all the bathrooms. It did not happen again. I think it is petty to mention this in a review as sometimes but rarely other guests make a mistake. They can let me know and there are multiple bathrooms. Mahsa's fuss simply humiliated the other guest and made him uncomfortable. Mahsa did no cleaning of the property unless it was after herself. Mahsa prepared all her meals in the house without problem but I had to ask her not to fry fatty mince as guest dont like the smells and meat fat pervading their kitchen. We think this is a reasonable adaption for a short term guest. It says so on the listing and Mahsa was told in advance but still bought beef mince. The maintenance referred to is a repair to a front path. This was done quietly at 8.30 by a single workman with no power tools and completed that morning. Sadly another 5 star review guest walked on the path despite signage hence it took 3 days to dry during which all guests entered and exited via the garden. On the night before (the bank holiday) I was cleaning until midnight at Mahsa's behest. I was then woken at 7am with Mahsa saying the gate was locked. This was not possible but Mahsa was in a panic and angry with me. However she did manage to open the gate. There was no sorry from her. Whilst I am sorry she was late for her course Mahsa chose to travel by bus instead of the faster train and tube in order to save money. I would have gladly refunded the difference to get her their on time. Mahsa arrived during late May and hot weather immediately asked me to "turn the heater on". I explained that the use of central heating would make us all uncomfortable and offered a space heater at the cost of the electricity as no one else wanted or needed heat. She declined and adapted to the house. We do not waste energy as a deliberate green policy.
Mahsa was charged £4 for a washload which is very low compared to the local launderette. She also expected me to hang out and take in her washing for this. Mahsa instead choose for the rest of her stay to hand wash her clothes, inconveniencing others and hanging them so that they dripped on the original wooden floors of the room. This was very upsetting but Mahsa chose to save money at any opportunity. It is the hosts duty to be fair. The room rate is extreme value for money. If guests chose to require extra services it is fair that they cover the cost of these. I cant comment on her current accommodation and what they include or not in the room price.
