Thanks Kristian and Annie!
It was a great trip in Madrid.
The apartment is perfect in everything.
The location is very close to metro(about 3min.), plaza sol and lots of sights in Madird(about 10~15min by walk). Annie was great host. Her explanation for restaurant and famous sights was very helpful for us.
The apartment was very clean, spacious and very comfortable.
I will exactly stay again this apartment next Madrid trip.
