Highly recommend staying here for any young people visiting Madrid who do not speak Spanish (Jhonson speaks great English) and want to be in the centre of town. It is not suited for a family, but worked perfectly for our trip. I stayed with my brother for three nights in July. The apartment could not be better located- just five minutes walk from Sol. It is super secure with four bolted doors between the room and the main road. It is very quiet for how centrally located it is. The Wifi worked really well and the bathroom was super clean. The beds were comfortable and Jhonson provided towels and even 'pillow chocolates' when we arrived. He was in contact the whole time and very helpful with advice about arriving. The air conditioning is very strong, so we used the duvet and blanket provided. We also used the washing machine and left it one morning when we went out. When we came back, Jhonson had taken out the washing and hung it out to dry for us. He was very kind, helpful and polite. I would definitely stay there again.

Bonus: I caught a new Pokemon every morning from just inside our room.
