The apartment is situated in the heart of Madrid. All sights are in a walking distance. The photos show the reality. The apartment is very well equipped. Especially it was nice that there were coffee, tea and even a bottle of wine as a warm welcome.
The communication with Lisa and his husband is excellent. You can always contact them for any question.
Although the apartment is good isolated, especially at the weekends it might be a little noisy (e. g. sirenes, people shouting in the streets) - but this is quite normal if you are in the center of a capital.
There is one point to be considered: if you sleep on the sofa in the front of the apartment, you should know that there are lights on all night in front of the apartment which cannot be turned off. If you only use the bed, it is nearly dark.
Summarizing if you would like to explore Madrid on foot and like to feel the beating heart of the capital, the apartment is ideal.
