The flat is not very sound-insulated. You can hear every step taken above and next to you. There's literally one door between you and other people. Also, the outside door can't be locked from the inside. So anyone with the combination to the front door could just walk in while you sleep; not a very nice idea. Same goes for the door between you and the adjacent flat; there's a lock on that door, but you can't lock it from your end. That just doesn't feel really relaxed. The bed is not too bad, there's only one not too big duvet plus a little fleece blanket. So on colder days you might want to bring your pyjama's. While you're at it, also bring a face mask if you want to sleep in the dark. 'Cause there are blinds for the windows, they just don't really block the light (we used the fleece blanket for that).
On the bright side, the location is truly excellent! Just a few minutes walk away from buzzing Angel. There are breakfast places all over Angel as well as restaurants with all types of cuisines. It's also very close to King's Cross. You might expect the neighborhood to be noisy at night, but it really wasn't! Positives for the flat itself: it has a small refrigerator, loads of storage space, a kettle plus some coffee and tea, and a bathroom with a great shower and bath. Towels were included as well as shampoo, shower gel and soap.
