Very comfortable and convenient! 1 block to King's Cross. Partial block to Tesco Express. The trade-off of location and being on the ground floor was that I could often hear the rumble from the Underground trains. It never woke me, but we kept normal hours and it was notable before we left around 8am each morning. The neighbors were not noisy.
We didn't do any cooking, but the kitchen setup was convenient for tea and leftovers. The wifi comfortably supported streaming youtube on the tv, but didn't reliably work on our phones in the large bedroom.
It was hard to tell from the pictures but there are 2 separate bedrooms. The small bedroom is between the front door and bathroom. The large bedroom has the 2 sliding doors and also a sofa, table, desk. From the large bedroom, you have to walk through the sunroom to get to the bathroom. The large bedroom has it's own door and is separate from the living-room/kitchen, which has it's own sofa, dining table, tv.
