Has anybody rented a short term apartment from Friendly Rentals in Madrid, or can anybody recommend specific apartments of theirs?

From their website, they seem to have some nice places.

I'm not sure yet that I want to go the apartment route on my upcoming week long stay. I recently rented an apartment for two weeks in Paris, and it had it's share of aggravation.

For only a week, a hotel might be a better idea, but I'm still deciding.
