Lucas place is the perfect place if you have a long lay-over in Madrid and need a comfortable bed and a nice shower before you head on.
We arrived super late (almost midnight) and he waited up for us and welcomed us in. He answered all our questions before we arrived always with a very fast response.
We took a taxi to get to his place because we arrived so late but in the morning there is a free bus:SE2 (while the metro is renovating) that will take you straight back to T2.
Make sure you stop for a Spanish breakfast at Obrador de Cardin (calle Timón, right before Burger King) about 200m from the bus/metro stop.
Definitely recommended!
