My wife and I spent few days in Madrid with 3 kids (9 & 11 years old). The place is VERY WELL located. Close to all important sites. Restaurants all over and a small supermarket next door to buy milk and easy cooking things specially if you are with kids. The City Tour Bus stop is one block away. The Subway station is also a block away. It has all you need for a stay. Carol E Ivan are very accommodating and reservations, check in & Check out was very easy. It is on the 4th floor and has no elevator, so be aware if you are carrying heavy luggage or if you can’t use stairs. The apartment is clean and modern. Also, be aware of the low ceiling in one room, but this is no way a deal breaker. We would stay there again if we visit Madrid, no doubt about it.
