Carmelo was the best host ever and we had a fantastic time! He took the time and gave us many useful tips about Central Madrid, as well as where to go, when and how. He is a really nice, friendly and welcoming person. His place is absolutely gorgeous (in my opinion) - authentic, original and comfortable. The neighbourhood is also brilliant - close to everything (literally walking distance). The apartment is located just off the main Gran Via street, but it is quiet enough to be classed as a residential area, in case you worry about it being too noisy. There are some really nice local restaurants and tapas bars within 5-10 mins walk down the c/Barco (in the opposite direction of Gran Via) - highly recommended, if you would like to mingle with the locals :)
