Our stay at Miguel's place was great.
Even though our flight was arriving late night, Miguel met with us and introduced us to the apartment.
Apartment itself is in a great spot (less then 15 minutes from Puerta del Sol, and within the walking distance of most of city's amenities).
It's in a great neighborhood, next to Tribunal metro station, lively but also quiet.
Apartment itself is really good for two person stay. It has more than enough room, kitchen and bathroom are great, and bedroom is really cozy.
We would recommend Miguel's place to anyone staying in Madrid.
