The apartment is in an excellent position, the center is easily accessible on foot.
Very silent, bright and sunny. Small but well organized and equipped with everything you need. The washing machine is useful and the laundry dries on the drying rack on the terrace.
The terrace, quite spacious and comfortable, is facing east and therefore sunny from morning to afternoon. It allows you to have a wide view and is pleasant especially in the evening (during the day, in July, it is too hot).
For security, access to the terrace is protected not only with a glass door but also with an iron gate.
Overall, an excellent solution to stay in Madrid. I will definitely return.
