The appartement is perfectly situated. Everything is accesible by walking and for further destinations, there are 2 Metrostations very close. The quarter is an upcoming quarter with little shops, but the Gran Vía with all of the big shops is around the corner, just as a supermarket. The appartement is lovely and looks exactly like on the pictures, there were no bad surprises.
Unfortunately I didn't meet Patricia personally, but she was very helpful, nice and reachable via Mail! In Addition, there were no problems with the keys, eventhough Patricia couldn't be there herself.
