Very good communication before the trip. The pictures showing the route from St-Pancras to the apartment make it even more easy to find the flat which really is only 4 minutes from the exit of the Eurostar station. Still the building is located in a quite street (we slept with open window).
We also liked the possibility to store our lugage before check-in and after check-out.
The collecting box for the keys may not be the most 'warm' way of welcoming guests but it is a very convenient way of making it possible to arrive at any time during the day. So if you are looking for a very close contact with your host, there are probably other places you could go to. If you are looking for a more hotel-like stay with the knowledge that a personal service from Sheng or Dido is available, then this place is a very good deal. Would we go back? Certainly.
