I spent 3 months of my internship at Katherine's places, and this is what I have to say.
As nice and hospitable as she is in person, her way of doing business is questionable, to put it that way - starting with the fact that I spent the first 3 weeks of my stay at her shared house instead of the studio I booked initially. Yes, we agreed on that in advance, but it was for 2 weeks only - the third week happened because of a "mix-up with dates", and she kept insisting that I stay there instead of moving to the studio at all. Moreover, what we also agreed on is a discount I would get for staying at the shared accomodation which I never received.
Moving on - the studio. As much wait and effort as it took me to move in there, I then had to put up with:
(1) pungent damp smell from the kitchen sink striking you as you enter the place, and toxic chemical smell from the bathroom which I had to fight by putting scents all over the flat (yes, I acknowledge that Katherine sent in some scents to help),
(2) really worrying bathroom - it had rust all over it. Moreover, later, I got a message that water was leaking to the flat downstairs every time I took shower,
(3) insects - centipedes (!!!) and roaches were my frequent visitors there,
(4) stove which was all busted up and ended up half-broken (2 out of 4 plates short-circuited and stopped working on my last day),
(5) the door lock got jammed twice - the first time I didn't quite get what happened as it looked like I was locked in from the outside, and I spent 1 day inside without any help (ended up figuring out what to do myself)
(6) finally, hard to say whether it was actually the room I booked (studio #17 on the listing, #14 on the street address, #5 is what I actually got), and it didn't have the all-wooden interior as in the pictures.
So why didn't I just report her to Airbnb and end my booking right there? The main reason was that I had to dive into my internship project right away and barely spent any time home - needless to say, a home like that wasn't helping much to ease stress of a very intense internship.
Katherine, I hope you think over the way you do business - I know you can do so much better...
