Though I couldn't meet Maik in person as he was not there during my stay, I really appreciated how he communicated with me and made sure everything was smooth during my stay.
Maik flatmates are quiet and lovely, as Dollar the cat, which is the most cuddly cat I've ever met.
The house is clean and spacious. The room is small but everything is there.
A note about the location: for me it was perfect as I was there to attend an event in Caja Magica. If you want to visit the city centre, it's a bit far. But the house is 5 mins from the Metro that takes you in the centre in 20 mins.
The value for money is wonderful. I definitely will come back to Maik's place if I will be back in Madrid
