We stayed in London for a few days and this apartment was not sufficient for 4 adults. We were dependent on using the sofa bed for an adult, but it was not intact and had a 2 inch thick mattress on it. The 2 bedrooms were comfortable and adequate for 3 people. You will need to bring your own basic necessities such as paper goods. The location of the apartment is okay and you must meet the greeter in person to gain access to the apartment. This unit is managed by a rental company, but the owner was very responsive when I made inquiries. This apartment has a washer and dryer which is a huge help when traveling.
