The apartment is cozy and welcoming, location is perfect indeed - the tube is 2 min walk from the building, Hyde park - 5 min. Many shops, market, cafes in the neighborhood.
Erkan provided clear instructions on how to get to the apartment and also gave some logistics advice which was very helpful. He replied to messages very quickly and was pleasant to communicate with.
Highly recommend to other travelers and will be happy to come back :)
