The apartment is very very good.
Great location: 15 min walking to many atractions, a bus in the entrance of the building, 5 minutes walk to king cross (one of the mains stations). Good space, confortable beds, good light and great kitchen provided with the basic for breakfast. The contact with Robert was ok, we were able to do the check perfectly.
The only thing to take under account is that there is no wifi in the apartment. Of course, Robert told us and we knew it in advance, but we though that it was going to be easier to find a hotsport arround. That was not the case in this area we were not able to find any wifi (nor free or paid , so when visiting Robert´s apartment if you do not have an international plan, you can consider buying a prepaid phone o something like that.
