The place is nice and great. You'll have everything you need here. To an Asian, it's important that near the apartment there's a lot Asian market so that I can have some food from Asia haha!! If you also like flea market or you'd like to find it out what's it, there's just one beside the apartment with 30 seconds walk on Sunday. This is so cool to me as I love flea market very much and it's a great place to spend your Sunday here:) the place is also close to the centre like Plaza Mayor etc.( just around 15-20 mins walk)
I will definely recommend to friends who'll travel to Madrid !
