We spent 5 days, 4 nights in Madrid at Izabella's place and really loved it. The space is very clean, private, quiet and modern with up to date kitchen and bath. Air conditioning was great and the beds were comfortable. Loft upstairs would be great for kids. The location is very convenient with some great local restaurants for dinner and breakfast (El Sur and La Infinito were our favorites for dinner and breakfast respectively), a 24 hour market at the end of the street, and 10-15 minute walk to Plaza Mayor and Puerto del Sol. It's a 10 minute walk to the train station and 10-15 minutes to the Prado and El Retiro. This was the second time we've used Izabella's place and would highly recommend it for a couple or family with young children.
