Well, you really cannot argue with the location - it's fantastic! You're right in the middle of the city and you can walk everywhere - we didn't use public transport once to discover the city.
We stayed here for a month to make our move to Madrid really simple and Marcos was an excellent and helpful host and he'll do everything he can to make your stay the best it can be.
Great shower, comfy bed, Netflix on the TV and surrounded by great places to eat, drink and hang out.
