Carlos was very responsive and nice. He would respond quickly to any of my questions or concerns. For example, the first night there the power went out in our apartment and he responded within minutes explaining to us what to do. He was very apologetic. The space was very nice, just as the pictures showed. However I’m not sure if I would recommend for a group of 6 adults. It felt a bit tight with luggage everywhere and 2 of the rooms were very small so bags had to be left in the living room. In addition, there was only one fan in the whole apartment. In the middle of the summer, that’s crazy! Sleeping at night was quite impossible because it was so hot. We would open the windows but it wasn’t very helpful. Opening the windows also welcomed a lot of noise from the neighbors, which wasn’t very pleasant. If there was a powerful fan per room then it would be great! Lastly, location was central to major spots like Puerta de Sol, Mercado San Miguel, and Atocha station to name a few. Thank you very much Carlos!
