I can just add one more positive feedback to the already existing ones. My friend and me had a super welcome: even though our flight was 3 hours late, Emilie reassured us and was there at midnight to open the door for us.
The apartment is soooo lovely.. Emilie took care of every single detail and made our stay perfect. Besides the room, Emilie and her husband offer a very good breakfast as well (Nespresso is available too :-P)
It is in a very convenient position, just a couple of tube stops from King's Cross on the Victoria Line.
I strongly suggest this host! Thank you again Emilie and Will for being so helpful!
