We were met at the apartment by Isabel, who showed us where things were and made us feel welcome. The apartment is very nice, spacious for our family of 5, and well-equipped. Quim and Isabel provided coffee, tea, etc. which is always appreciated in the mornings. The first evening, I sent Quim an email asking how to turn the heat in the apartment down as we like it a little cooler. Within 10 minutes, someone was at the door to show us how to control the temperature! It is helpful that they live in the building as well. The apartment is an easy 10 minute walk (with bags) from the main Atocha train station, so very convenient. Also some very good restaurants close by, and close to major museums and metro. We would stay here again if our travels bring us back to Madrid.
