I stayed at Tricia's place in the midst of the pandemic, and I am so glad I did not opt for university halls instead.
Her house was always very clean, she took the virus very serious. The room and the house are just as described, guests are also welcome to use the garden. The room itself is on the smaller side, but has a lot of storage and there are also multiple bathrooms in the house.
Overall the best word I can use is homely: Tricia is hospitable and genuine, everything is
well taken care of and I had a lot of space to live my own life without feeling like I was constantly living at a stranger's house (even though I technically was).
If there were smaller problems - not knowing how to operate the laundry machine, or how to seperate the waste (as that differs greatly from country to country) - I could always bring them up or Tricia would tell me straight away to avoid confusion in the future. I think communication between host and guests is really important, and with Tricia it was always very easy.
The house is located in the south of London, so there will be a bit of time spend on public transport if guests do not have a car. There are bus stops around, yet it takes a while to go to the centre of the city. The fastest way would be taking the train.
On the flipside, the area is also quiet and not as busy as other parts of London.
I really did enjoy my stay there, and Tricia's company as well, and wholeheartedly recommend this Airbnb!
