We stayed here in March with two kids (3,6).
There’s probably no other apartment in central Madrid which makes a family instantly feel at home.
The dining table was great for a big family. The kitchen equipment is really good. The kids liked the games and the toys.
It was also really warm and cozy in the apartment - which is not always the case in old Spanish house. The terrace is also really nice.
And it was quiet at night - even when the bats are busy.
You can feel that this house has been decorated with lots of love.
I would come back anytime.
