We had the most wonderful time in Madrid. Sergio's apartment has the perfect location where from you can walk through the lovely Park Retiro to most of the best museums and other exciting parts of Madrid. We arrived very late, around one in the morning, but this was no problem with Sergio who we met without any trouble at all. Given the late hour, Sergio gave us a quick introduction to the apartment which had everything we needed and more- Sergio had even filled the fridge with everything needed for our first breakfast. Sergio is a warm and kind host and we will definitely recommend a stay in his beautiful apartment. We will hopefully return to Madrid soon and I will not hesitate to contact Sergio again.
