Fantastic space in a great part of town minutes walk from anywhere. Spent 5 days as part of a large group trip.
The place was fantastic with loads of space so as to not feel overcrowded and plenty of bathrooms to help getting out and about in the morning. Seamless communication both before and during the stay with the hosts being very accommodating to people arriving and leaving at different times.
Will be certain to look this place up again when returning to Madrid.
