John was really helpful. He recommended us a lot of things before our trip. He was willing to help us at any time. The appartment is located in the best area of the city if you want to visit it. It is also very close to the Central station (less than 10 minutes walking). The appartment is exactly as you can see in the pictures. The only inconvenients: there are a lot of stairs to arrive to the appartment. Inside the appartment there are 20 stairs to go upstairs. The check in time was at 4.00 pm and the check out at 11.00 (we couldn't leave our luggage so John recommended us a place in Central station to leave it). The rest was just perfect.
