pros.
location - amazing, close to hyde park and tube station
landlord quiet responsive and helpful
cons.
noise - windows constantly rattle, floors are very creaky, upstairs very noisy. estate agent downstairs sensitive to noise, beware if you have kids
size - pictures are a bit misleading, size is smaller than pics look
we had an issue with the heating, took 2 days to arrange to fix. then landlord allowed engineer access without my permission which wasnt great.
cleaning wasnt great either
