We had a great stay here in the flat, it had everything we needed for a two week stay during business trip. The apartment was nice and it looked like it had been relatively recently after the renovation. It is placed in quiet neighborhood, with many pubs and groceries in the vicinity if needed. Also there is just 15 mins to the underground station, which is only one station away from King's Cross.
The only potential downside was a elevation renovation outside the building, but since we were mostly out, it didn't really bothered us. Also the washing machine was broken, apparently we were the first ones to discover it. The owner tried to took care of it, he sent a service to tried and repair it (futily), and also offered us assistance with linen delivery, but we chose to go to nearby self-service laundry. Best to my knowledge the washing machine should be replaced anyway.
To sum it up, I can recomend this place as it is both convieniet to live in but also is well connected to the rest of the city.
