Duncan was not lying about those cats, they really are friendly and they actually feel like its their home because when doors of the terrace are open it is a 99% chance one of the cats will casually walk inside. But no trouble, unless you have allergies lol.
Terrace, by the way , is really spacious and when you open the doors the whole apartments feels very fresh. There is also a calming view of the river. I very much liked the terrace. Design of the apartment is interesting and creative. I guess Duncan surfs, I strongly support that :). Kitchen is well equipped. Bed is very comfortable. Center of the city id say 10km distance? Well, depends where you go.
The only thing that was a bit disliked is that people upstairs wake up earlier than me and I could hear them pretty well and was forced to wake up earlier. But if you wake up before 9am, there should be no problem for you. There is a construction not far, but there was no noise from it almost at all. Also, I wish Duncan would free his apartment a bit because there is such little space to stack your things. (I had 2 luggages of clothes)
Communication was on point, whenever I had a problem Duncan was there to answer within couple of minutes. Thank you very much, best wishes to you!
