This place is very nice and cosy, as you see it in the photos. It was perfect for the four of us, close to King's Cross station and places to get food, or if you prefer there is a Tesco by 3 minutes walk.
We did not get a chance to meet Evelina, but she arranged everything for our arrival and gave us clear instructions to enter the apartment. Also, Adam, his neighbour was very helpful in answering our questions.
The apartment is on the third floor, and as mentioned, the building does not have an elevator but this was not a problem for us.
