Location! Location! And location! I had been to Madrid before and I knew what I was looking for this time. The apartment is located right on Calle Mayor and Plaza Mayor, and Mercado de San Miguel. These were exactly what I wanted. The check-in process was very smooth. Enrique and Jorge were very friendly and communicative, and Enrique was at the apartment waiting for me on my check-in day. The internet was fast. Overall, I had a very nice stay there.
