I can't think about any negative aspect of my experience to write in this review. Jen is the greatest hostess. She was super helpful since the first contact and replied almost immediately to our messages (plus, she was very patient and understanding when our shitty Vueling flight was delayed almost three hours!).
The apartment is even better than the photos depict. Cozy, recently refurbished, and decorated with great care to the smallest details. Comfy bed (with many pillows and cushions) and a nice shower. A few meters from Gran Via, it's pretty close to both Gran Via (3min walk) and Callao metro stations. You can also reach Puerta del Sol and other touristic attractions within a short walk. Sure Shot!
