Fantastic location! Walk just 1-1/2 blocks to Puerta del Sol/Sol station (with Metro, buses, and Cecanias train) or to Plaza Mayor. Walk 10 to 25 minutes to Thyssen, Reina Sofia, Prado, Archeological museums and to the Royal Palace.
The apartment was roomy, comfortable, well-appointed, and clean. It also felt very secure due to the locks, inner entrance, and window locations.
Tea bags, coffee, salt, pepper, laundry detergent, vinegar, and salad oil were provided.
There is a very large discount store across the street, similar to a dollar, euro, or 100 yen store!
Not advertised as for non-Spanish speakers, but the co-host, Jose, helped me in English.
Very highly recommended!
