We stayed with 4 people in Jonathan's apartment. Jonathan has outsourced management bookings to My property host, and the communication with Ash went very smoothly.
The penthouse is fully equipped, and has an amazing view. The finishing is luxurious.
Keep in mind that you have to arrange a number of things yourself, including toilet paper, kitchen paper, hand soap, but a supermarket is around the corner.
Exactly 4 sets were available of tableware and cutlery so we had to use the dishwasher often. It is more convenient to have some extra pieces of dishes and cutlery.
A big disappointment was the wifi. We had expected unlimited high-speed wifi in such a luxury apartment, but the connection was slow and spotty - every day wifi was disconnected. We had to contact Ash daily. Additional data was then added or instructions were given to restart the router.
On the last day they lift didn't work walking up and down 7 floors was a kid was no fun but luckily Ash responded quickly to our messages and arranged for someone to help us carry our luggage down when checking out, so that's nice.
Location wise it was great right in the thick of things in Shoreditch surrounded by lovely markets and restaurants. Though there were some slight issues that could have happened in any apartment their quick response and service to fix it made all the difference.
