Fantastic location, only a few minutes walk from Picadilly Circus, Oxford Street, Regents Street, etc.
Place wasn’t sparkling clean but not dirty either. Can get quite loud in the evenings because there are bars and restaurants nearby.
Kitchen is a bit small and missing things like a draining board which can make it hard to cook, but perfectly fine for breakfasts and stuff.
Overall, small but cosy apartment with a big window overlooking the square. The main selling point is the location which is perfect.
