The location of the apartment is perfect, 5 minutes away from the metro and train station so you can get anywhere in a short time, all the museums and parks, except for the royal palace, are at walking distance and there's plenty of restaurants and grocery shops nearby. The host was very welcoming and was available at all times in case there were issues. The three rooms are small but not in a bad way, there's plenty of space to lay your luggage and personal stuff. The two bathrooms are nearly identical and are equipped with plenty of towels both small and big and you can dry them in the internal "balcony". The only shortcoming I can think about is the fact that the kitchen doesn't have any cooking utensils except for pans and pots so cooking can be difficult and restricting. 10/10 would recommend to friends and family, should I go to Madrid again I would book the place again.
