This apartment is really, really small. I dont know exactly how many m2 it was, but it felt like maybe 12. Certainly consider it a small room with a kitchen and shower rather than an apartment.
The bed is also - really small and not very firm, so with 2 people, expect one to be sliding off it. The bathroom/shower is super cramped and the shower only has pressure on cold settings. There was no shower matt so floor water after a shower was immediately a problem.
There was a kitchen, but no salt or pepper or oil. If you wanted to use it, you would need to bring everything. There is an M&S within 5 mins walk though, and a Queens Park is super close.
Check in was not the same as the instructions. It was not clear which apartment was actually meant for me. There are a number of tiny apartments in this building and it's pretty run down. You needed to lock the door with the security key, otherwise anyone could just open it and be in your room.
It smelt a bit old/mouldy/cigarettey, but the apartment itself was clean, it's more just a wet, London smell that some flats have, this one had it.
I ended up leaving early, it just wasn't really comfortable. For the price I would recommend a more central hotel.
Host was polite, answered within an hour, no issues there, just a very, very small and not very comfortable space.
