Helen’s place is in a great location in Bank. Very conveniently situated between two tube stops. The flat is in a larger apartment/condo building with a doorman which was helpful.
We stayed with 4 people and utilized the pullout sofa (which was quite comfortable). We had a slight issue with lack of hot water but luckily Helen quickly had the management company fix it after we contacted her.
Would recommend Helen’s place to other parties of 4 or less.
