I had a very pleasant stay!
The location of the apartment is amazing: The neighborhood is full of lovely bars, restaurants and cafes. There are two different metro stations nearby.
The apartment was very spacious and clean. The bed was very comfortable. The kitchen had all necessary utensils to cook during a longterm stay.
The hosts were super friendly and flexible, responding quickly to any massage and helping me however they could.
I had a great time in Madrid and would highly recommend the apartment!
