The kitchen has clearly been the focus and that is quite nice. The rest is only okay.. fairly clean and functional, but a bit cheap, with some rough edges. The real negatives though are twofold: the external appearance of the block (broken glass, and an abandoned fridge freezer in the garden - a risk to children) and the apparently nocturnal neighbours upstairs. The latter is a particular problem if you are trying to sleep in the front room, so I'd suggest this flat might be better for 1-2 guests in the main bedroom, not for 3 or 4 including the sofabed.
Overall, fine but not the best value for money - slightly wish we'd stayed at a Premier Inn instead.
