Marco was very nice to us! He is very polite, always had something to say if we found him in the kitchen or during the morning before we left to visit the city. He never took too much of our time but casual conversation is always good to get to know each other better.
About the house: The location is amazing, you have two different metro stations nearby (Sol and Banco de España, line 2), also Plaza Cibeles is about 5 minutes walking (during late night a lot of buses stop there), finally you have an express supermarket 5 minutes away (also walking).
Our room was bigger than we expected! A lot more than what we actually needed, so it was great! We had a private bathroom with modern furniture. The water pressure and temperature is better during some parts of the day, so if you're staying here: try to avoid rush hours to take a shower.
We used the kitchen several times and we had everything we needed!
Finally, we really want to go back to Madrid and stay for a few more days. Marco is going to be our first option, of course!
Thanks for everything!
