Really nice and stylish apartment...me and my family had a great time...The Location is perfect...close to a lot of nigh bars lol...there is a Metro station literally 30 sec away...basically you are in the middle of the Historic city of Madrid...everything is like 10-20 min walking from you...
The only negative is that the apartment is located on the 4th floor...and there is no elevator...so be prepared to climb some stairs lol...
I'll definitely stay again there if i have a chance !
