The place is great, clean and big enough to accommodate 5 people.
It has 2.5 bedrooms (2 full beds and a pull-out couch), 2 full bath rooms and a full kitchen with dishwasher and washing machine to clean your clothes. The living room has a big with a dining table that can sit 6 people comfortably.
For entertainment the living has a flat screen TV and wi-fi internet was available as well. The building was quiet and very centrally located close to Sol and 10 min walks to the Prado, Plaza Mayor, Presidential Palace and lots of restaurants all in walking distance - we never took taxis or Ubers.
The only negative - and this is a general one - is that the streets of Madrid can be loud at night. Thus the closer you are to the center of Madrid the more likely you'll experience the street noise.
All in all, we were very pleased. We had a great stay with no problems and we would AirBNB this property again.
