All communication with the host was conducted in a most professional and efficient manner. Access to the property at check-in was very easy. The apartment is slightly dated in its decoration and fittings but is clean and the bed most comfortable. The heating system is not very modern but, thankfully, it wasn't needed very much during my stay. The hot water supply is excellent as well as the shower pressure.

Positives:
The location is very good. Close to Baker Street yet located on a quiet street. Very little noise from traffic, passersby etc

Negatives:
The wifi hardly worked for the duration of my stay even after having reported it several times.
Due to a drain blockage (and rain) there was a huge puddle outside the entrance. This got larger after a few days and started to smell bad. Not a very pleasant thing to encounter when arriving at or leaving the flat.
Some lights in the kitchen should be fixed.
Make sure you shower carefully as to not let water spill on the bathroom floor.
It is very difficult for towels to dry in this apartment.
