I stayed here with my parents and boyfriend for 5 nights. It was perfect for us. The kitchen is adequately stocked for basic cooking needs, the beds were comfortable, plenty of space. The flat is very easy to get to from the Plaza de España metro stop and the Madrid City Tour hop-on/hop-off bus stop number 9 is practically right out the front door and downer the steps. Loads of small restaurants are all around (less touristy and more local-feel) and Gran Via is just a few meters away for a more lively atmosphere. Despite its central location, the flat was extremely quite and very cool (likely perfect for hot summer stay). I'll definitely be keeping this place on my list for my next trip to Madrid.
