Madrid was an awesome experience!
Thanks to Carols Apartment, which js right in The Heart of The City and in The Quarter named "Sol"it was easy to get anywhere from there.
There Are tons of Shopping Opportunities, Bars, Cafés and Restaurants nearby.
It is also just some Meters of The Metro apart.
The Apartment is really comfortable for 4-5 persons.
I only can recommend it for anyone who want to have a Great Time for Less Money!
