We enjoyed the apartment. It is very spacious and has all the amenities required. Kay was very responsive. The self-check in/out was easy. Our only disappointment is the location is actually 20-30 minutes walk from any tube station. It was easier to take a nearby bus into the city center (~30 minutes). Still, the 1 hour round-trip journey meant that we couldn't come and go easily throughout the day, for a rest or a change of clothes. Once we were out, we stayed out for the day. If we were doing it over we would probably stay closer to the tourist center.
