Amazing gem of an apartment!
The location is wonderful- right in the middle of the the cute shops/restaurants/bars in Malasana, but within easy walking distance to all the major city center sites as well. It's quiet, with a nice street view, and 2 grocery markets a few steps from the door. Within a few minutes walk you can be in the middle of all the business/craziness of Gran Via, big stores, etc- but the charming and unique neighborhood of Malasana has a new charm at every corner.
The apartment is perfectly curated and appointed- everything you need, including dishes/silverware/cooking stuff, as well as laundry detergent, etc. The A/C works great and cools down the place quickly. Bathroom is quite large and love the space to store things in the bathroom sink.
My only regret is that I'm not coming back to Madrid soon enough!
