Overall great price for what you get. It's around a 25-minute walk to Trafalgar Square (longer for Chinatown/Leicester Square). The surrounding area feels safe.
The Airbnb itself felt more like a hostel - there are two other rooms which share the same kitchen (which was quite dirty especially the fridge), and our door did not have a lock. We were a bit surprised at this because there was less privacy than expected. We were also surprised that the washing machine/dryer were located in the other tenants' bathroom. The dryer does not work (our clothes still wet after 3 hours of drying).
The floor and rugs in the place were stained and dirty, and there was a musty smell when we first arrived. The shower drainage is very slow, and the toilet needs to be flushed a few times before it works properly.
The host's communication and proactiveness was brilliant. The hairdryer did not work and she replaced it for us within a few hours. Overall, would stay again but wish we knew the above.
