Great host and location...
Paula was supereasy to deal with and she met us at the place and helped us check in early. The location is great 7 min walk to underground, bus no 7 will take you to Marble Arch in 10 min - great as a hub for exploring all of London.
We were a family of four with older children. The sleeper sofa in family room was really good - firm mattress and great space. My son slep in one of the double beds and he had no issues. My wife and shared one bed and the mattress was not great and could use an upgrade. Kitchen was good - fully functional. Bathroom had plenty of hot water but could use a deep clean or having some of the grouting etc.. redone.
Overall - the apartment is very typical for London. It is in an older building and it is good value for money. If you want a high end experience, you need to pay a lot more..
