the place is small and has every thing you need for a vacation.
It is not in the old center of Madrid, but in the metro it's really easy to get there and takes like 25 minutes.
They both did every thing to make sure we are comfortable and fill at home. helped us alot with anything we asked for. very nice people. i defenetly recommend. if I come to Madrid again this will be my choice.
And don't worry about the cats and dog. they are gentle and lovely and really don't bother you. (we wish they would bother us more...)
