All in all we had a very pleasant stay, although there was also a miscommunication. The appartment is spatious and all facilities are present. My only minor complaint would be that the bathroom is less spacious.
The location of the appartment is very convenient, everything can easily be reached by tube, although the location is also very noisy. It is in the middle of the party district in Soho, although this might be what you are looking for.
There was only unfortunate miscommunication, I was given the wrong key and appartment address, so for the first 2 days I stayed at a smaller appartment and had to relocate (including repacking my bags). I have not been given a reimbursement or a formal apology, but all other communication was friendly.
