Carolina is a great host and made me feel welcome at Madrid during one of the peak times of the year , i.e. New Year's eve. Despite the linguistic differences, she was very helpful in explaining everything from reaching the place from Madrid Atocha station to the house rules and finding attractions in the surrounding neighbourhood. She even recommended places to visit for the ensuing portions of my trip. I would recommend her place to solo backpackers without doubt 😊👌.
