my wife and i travel to madrid frequently, so know all the best areas to stay. The apartment is in a very good location, although it is court yard facing, the advantage is that it is very quiet on an evening, but litterally being one minuite from the Gran Via. The apartment is as described, in excellant condition, spotlessly clean, very well decorated ,and equiped with all that one would require .
At the moment, several apartments within the building are being renovated,therefor builders start work at 08:00 and finish 18:00 - 19:00, so expect noise, the main foyer is dusty, however the builders do clean down at the end of the working day,in addition they run temporary electric cables to supply cement mixers etc, so be aware of trip hazards.if you can live with the builders times, then as said it's in the right area for those to explore madrid with ease.
