For one night, it was comfortable enough. Our group of 4 settled on 2 stars though :( rough around the edges.
Pros:
You won't be cold, insulation is perfect.
Location is also great, tube entrance 14 minutes away by foot.
Area feels safe.
Brightly decorated.
Surfaces clean, appliances clean, sink nice and clean.
Cons:
4 guests, but only 3 beds set up on arrival. We had to figure out the sofa bed ourselves and find the bedding in other rooms.
Spare bedding for sofa-bed seemed dirty (few hairs, bits of fluff).
Not enough towels provided.
Near-empty containers of coffee, shower gel and sugar from previous visitors (no welcome pack in case anyone's wondering).
Needs TLC. Small leak for kitchen tap, bathroom sink partically blocked, scars from prior water damage on kitchen ceiling.
Struggled to adjust radiator temperature, but this one's probably just user-error ^^'
With a little change it'd be a great place, would stay again if changes made, rather wait a while though.
