Our stay at our host's place was fantastic. We traveled as a family of 4 with 2 teens. We all had our space to spread out. The primary bedroom had a half-bath, which made it very convenient for a family of 4. The bunk room was small but served its purpose of sleeping, which is pretty much all we did when we were inside the apartment. Our oldest chose to sleep on the sofa bed in the living room. The only negative was that the hot water would run cold by the 4th person showering. We learned that after the first couple of days, so we adjusted during the rest of our stay.
The location was great - it's across the street from Mercado San Miguel, The Plaza Mayor and Plaza del Sol are just about a 5-minute walk away, for lots of activity and shopping. The Royal Palace was also just a short 5-7 minute walk. The metro was close by and convenient for sites that were further away. There's a small supermarket, drug store and cafe for coffee right on the same block! Great stay!
