We really liked Jorges apartment. Its located within an old hotel building, I would assume, where they made just airbnb apartments out of all the rooms. Therefore they are reasonable small, but equipped with everything you would need for a short stay - even a kitchen. The checkin was quite easy by entering with a code provided and the apartment was clean and tidy. The location is super central and you could basically walk to every attraction within the old town of Madrid. I have to specially mention that Jorge and his team let us shorten our stay since we had a medical emergency in our family - so thanks for that. I can definitely recommend this place!
