Before our arrival, Mike sent very clear and detailed instructions on how to reach the flat, and suggestions of what to see and do (his lunch suggestion of "Terra Mundi", about 20 minute walk away from the flat, was excellent). He seemed very well organized and he always answered my emails very quickly. The apartment was exactly as described and very charming. There was air conditioning (very important in Madrid, in August!), and even a washing machine. The apartment is situated in the old part of Madrid and it very easy to walk to everything that we wanted to do. There are many fun bars and restaurants very close to the apartment, and it's about a 15 minute walk to the Prado. My friend and I just stayed for two days, but we wish we could have stayed longer! I would not hesitate to stay with Mike again if I ever came back to Madrid.
