The location of the apartment is very close to Atocha, which is a big plus. Even though the apartment offers good value for the money, it's pretty basic and it will only serve the purpose of spending a couple of nights there with no problem (because of the great air condition and two separate bedrooms). We had a couple of problems from the start including the broken fridge (which we needed and lost some food in the process of finding a solution) and broken sofa bed (which we didn't need so it was not a problem) - probably happened to people who rented the apartment before us. Luckily communication with the host was more than great and we managed to solve most of our issues in reasonable time. We would not return, but it doesn't mean you should not come if it fits your needs and budget. Enjoy Madrid!
