I cannot recommend Edu’s place any higher. The apartment is in a fantastic area of Madrid and is close to everything you need/want to see - anything outside of the city centre is easy to get to as a metro station is 5mins away. Bed is really comfy and the bathroom and bedroom is super clean. The kitchen is clean and fully stocked, with a fridge for all occupants to share - some items such as pastas, rices, fruits and snacks are communal. Further, soap and shampoo are provided during the stay.
Fantastic stay, and I would stay here again if I am ever in Madrid again.
