Juan's flat is perfect for long short or long stays in Madrid. I was there for 10 days for work, and everything was perfectly adapted : quiet and large apartment, very central, good metro/bus connections, nice area for having diner, comfortable beds to sleep... Juan rules a café just down the building, perfect place to have breakfast (I had it there everyday !). And, last but not the least, Juan was very reactive in any case of problem. Great address to stay in Madrid. Gracias.
