We had an amazing time in Madrid and in Juan's aprt'!!
The only thing that made it a little bitter was that on checkin Juan was not in Madrid, he got confused with the dates and so the aprt' was not ready and we needed to wait with 2 babies at 1am till his employ will come to give us the key and to clean a little cause ppl were there in the morning.
The aprt' is big, one shower is little and not so comfy and one is great. The walls are thin so we could hear everything from the other rooms and the other aprt'.
The location is AmazinG!! You don't need to use the metro/bus/subway to get to all the good things in Madrid cause everything is so close and you can walk!
Had a great time!!
