We live in Flat A. Been here four years.
Flat A: £1,500 a month, 45sqm, 40 minute commute on the tube, very tired bathroom and kitchen.
Flat B: £2,200 a month, 70sqm, 15 minute walk to work, brand new bathroom and kitchen.
£8,000 a year extra in rent is a lot but easily affordable. Flat B is not somewhere we would buy so would be a fun experience
