If that´s the address then it is in Madrid.
I have been there two times and both were a dissapointment. The chef has changed again and now they have better reviews.
For the same price range I´d go to Aldaba, Alberto Alcocer Esq. Dr Fleming 34 913597386.
They serve Basque food. The fish and the meat are excellent. Fresh as they come. The wine cellar great and the sommelier a very learned man. Setting is elegant and discreet. I´ve been a fan for 6 years and I still enjoy it. Price for two including wine (dessert too) 140 Euros approx. Good luck!
