This place is perfectly located for all who wants to visit Santiago Bernabeu!
This place is the cheapest one in the area - remember it when reading next sentences ;)
The stadium you can see when getting out of the building - it's in the walking distance of 5-8 minutes.
In general apartment makes wow effect but there are some disadvantages you should be aware of.
It's on the ground floor what makes it very accessible - when you forget something for sightseeing you can come back and grab it within 1 minute. That's great!
When outside you are already in the heart of Madrid, shops, cafes, restaurants, and so one.
Those who want to watch TV will be disappointed, there is no TV (for me that was advantage ;))
It's very noisy - the window is on the street (on ground level), don't count on silence :) Depends on what your goals are and what time you come back ;)
But remember what I wrote at the begining - still it's the best offer in the area from economy perspective :)
Willy is very nice and good man, he's very helpful. The communication may not be easy however for non-spanish speakers ;)
In general it was very clean in this tiny apartment, I had a good stay there with my son.
