Stop your seach now! This is by far the best place I've ever stayed in Madrid. My wife was impressed how cosy and charming the place was. We love it.
It was much larger than expected and has been remodeled beautifully.
When we arrived she welcomed us personally and even carried one of our heavy bags up the three flights of stairs! There were snacks and drinks provided, and an awesome list of recommended places to visit. Also a map with routes traced which we loved. The apartment itself is a jewel,in a lively neighborhood with tons of great shops and restaurants around, in a great location. We can't say enough about the apartment itself. Gorgeously decorated, and quite large. Loved all the photos, decorations, lights and quirky touches. The blue bathroom is a gem, and the original design mixed with the modern remodeled touches made it perfect. We especially loved being able to open all the balconies and let the sound in from the street:)
