After finishing my master course at Sep 2018, I stayed in Shirely's place for nearly 4 months until my visa expired yesterday. Shirely's apartment has a perfect location that 3 mins to Marylebone station on foot, 7 mins to Baker st station.
It is not only a flat which is good for short staying, but also brilliant for the people who would like to stay in London for couple months, Shirely's flat has a Tesco nearby and it just take 10mins by walk to Marylebone high st, at there you can basically find various high quality ingredients if you enjoy cooking.
Shirely is a perfect landlord which I meant kind, friendly and always quick response, no matter you are seeking for a place for short or long staying in central London, I strongly recommend you contact Shirely !!
