What a great and wonderful place. A real gem in the heart of Madrid. The location is perfect. You can take the bus or Metro. All stations are within walking distance. The airport is about 20 min away with an Uber (~20 €) or cab (30 € flat). There are plenty of supermarkets around and even a traditional food market across the street. The closeness to Gran Via makes it perfect to start a new day exploring Madrid. The apartment is perfectly styled and has everything you would want in your own home. The fully equipped kitchen and the big TV screen with Netflix would let you want to spend a night binge watching your favourite show. The bed is very comfortable and very clean. So are the two bathrooms. One even has a bidet. I enjoyed every minute of my stay and would love to come back anytime again.
