very nice place at host's personal apartment, full individual bathroom for your self, nice comfortable couch/bed.
nice balcony, kitchen and tv room to share with Carolina (not for your self alone as I thought).
it's a big 3 story apartment close to a Metro station and literally 20 min from puerta de Atocha (city center).
everything was great, Carolina is more than happy to help you but the sheets, floor and shower were full the previous guest's hair.
