I stayed at Nqn after it just opened in February 2023 and it was a fantastic experience. The renovated building is right in the centre of casco antiguo making it a perfect base to explore the city and close to Aldi nearby if you intend on using the kitchen and fridge. The room was brand new with a spacious bathroom, comfortable furniture, a functional kitchen (minus stove), TV with sports channels (la Liga, premier league) and despite being in a busy location the soundproofing was excellent. The rooftop terrace is the highlight with beautiful views particularly west and south looking to the cathedral and la giralda, there is also a small pool. Check in is easy and Froilan and Julian at the front desk were always helpful, responsive and easy to deal with for anything required.
