The landlady was quite enthusiastic and kind, i suppose she waited for us for nearly 1 hour and still be patient with us.
Even though she doesn't speak english she could tell us some tips about madrid, which is helpful.
But when we wanted to take a shower we suddenly found that the hot water didn't work well. So we just couldn't got a bath :(
Later we also found that the hairdryer doesn't work .....

But the next day the hot water worked again. Thanks god.
btw, here is a little bit far from the airport if you take the tube.
But here is just 5mins walk to the nearest tube station , delicics.

One more, the bed is clean.
Anyway, not bad.
