It's a one-room studio apartment with a balcony. A bit on the small side, but has all the comforts you would need for a visit to Madrid. The Ibiza neighborhood is really great and has lots of excellent bars and restaurants and is super close to Retiro Park. We went for a walk there every day. There isn't much of a table/working area if you are planning to visit on business and need laptop space. Other than that, it's very cozy and should be suitable for most visitors.
