HIGHLY RECOMMEND! Perfect location near plaza de major(1min apart from metro station "opera"/ right in front of market), well organised and equipped(hair dryer, air conditioner, toaster, towels, tablewares, pots etc)
And host couple is warm hearted and so delightful. Though it's on the 5th floor without elevator and wifi connenction is a bit weak, it helped me have beautiful memories in Madrid! Thanks a lot :)
