Shalin's flat is really nice and convenient, it is exactly as described in the website, good location and tidy. He created a WhatsApp group because he would not be available to give me the keys on the day, so he would introduce me to the person who was going to give me the keys.
Would recommend it to anyone, there is a shop right in front of the place, some pubs nearby and it is a nice walking distance from King's Cross station.
