Helen's apt is in a great location and she is very responsive, however, the apt is lacking charm and requiring updates.
The flat is very close to the underground tube and the vibrations and noise from this is quite noticeable. Luckily, the tube does not run throughout the night, especially when travelling with children.
The outdoor area was directly in line with the neighbouring office building. This was not a problem for us, however, it was very dirty with multiple cigarette butts thrown about.
The sofa/pull out bed was not usable. All 3 members of my family could not sit on the sofa at the same time. The pull out bed was in such bad condition that my 5 year old was unable to sleep on it. I spoke to Helen about this and the alterative was a blow-up mattress, which was less than desirable considering the cost of the rental.
