Marta is really a hospitable host, who always reply my questions nicely and in time, and take care of all our needs although we got no chance to meet her in face. All rooms are comfortable and all equipments work fine during our stay. The location is extremelly convenient to take subway or walk to Plaza Mayor and El Rastro. All in all, my friends and I strongly recommend Marta's place if you would like to have a wonderful time in Madrid.
