We were 3 guests. The apartment is ok. It's definitely looks better in the pictures. The balcony was not clean at all, the chairs and the table were dirty and there was a lot of garbage on the floor - even cigarette butts and some unrecognised bones.
Note that the smallest bedroom has no heating - which is very needed in London during winter time.
If you are tall (which we were) the shower-head is low so you will need to manage it.
The blanket cover could not be zipped and while we're sleeping its cover fell and revealed a blood-stain on the blanket itself.
Location is great. The apartment is only 3-minutes away from the Northern Line and you could reach the Soho area by foot (30 minutes)
Overall I give the stay 4 out of 10.
