Based on the site, they've had a pretty big refurb. We negotiated the price down a lot, think we got the largest unit for 16k (24k for 6 weeks), and we didn't need to pay a deposit.
I'm currently in a Dorsett (LKF) for the quarantine period. It's well set up and clean, but if there's 2 of you in one room, you might well end up going mad. The Room is not huge and there won't be anywhere for you to hide for some me time apart from the bathroom.
They are doing 45 night packages at a heavy discount which would enable you to use it as a base (they give you a new room after the 2 wekks quarantine) while you search for something.
I'm in the 'meals included' package so get breakfast from the hotel each morning (day 4, it's just depressing now) and a diet of 'rice and' for lunch and dinner - I've attached the menu.
Definitely get Deliveroo and Food Panda for pretty much anything to be delivered to wherever you end up.
Plus side for me is I've stopped eating quite so much, read three books and done a ton of research before I start my new job. Flat hunting is next up so I'll be reading the whole subforum on that....
