really loved this apartment. it is situated right at the city centre with all activities at proximity, all places to visit are easily accessible from this location.
the metro stop is just a minute away with lots of restaurants and shops. it is actually a very good location to stay when visiting Madrid.
the only bad aspect is the caretaker speaks only Spanish so it's difficult to communicate. Also they waited till the very last moment to give us the code and access to our room which was frustrating at a point.
apart from this, I would recommend this apartment to anyone visiting Madrid
