Nu was a wonderful host. We were able to drop of our luggage after 12 even if check-in wasn't before 16. This was great because we came to Barcelona early with 3 small kids and a lot of luggage. Great location. Only a 20 minutes walk to La Ramla and all the cozy little streets towards the Old City. The appartement itselfs is located in a noisy street, but when you close the doors to the balcony it is quiet inside.
We were 7 people included 3 children between 10 month- 2,5 years and everyone loved the appartement. The host Nu even let us check out late because we had a late flight home. Highly recommended.
