Hello Mia
From my personal.point of view I have not used any of the property management companies however, I am a co host for 9 hosts in Kensington and Chelsea / Westminster Boroughs and 50% of them have used one / all / similar companies.
The hosts I work with contacted me as they needed a more personalised, consistent and reliable not to mention 'more bang for their buck' service.
I work with other hosts where possible to compliment and deliver an authentic service. I think there is a lot to be said for being part of the hosting world myself. I know the pressures. As a superhost I know what works. Have a look at my airnnb profile. You will be able to see see some of the properties I work with.
I am very happy to have a chat and see if I can help in any way. My number is
07939 100336.
Regards Margaret
I look forward to hearing from you.
Margaret
