We were very happy with the appartment and de way we were received by Alina. The appartment has 3 bedrooms wich was very convenient for our two girls, who are used to sleeping in their own bedroom. The appartment was clean and everything you need to prepare a simple meal was present. Free wifi worked great.
The Carrer d'Arago is a busy street, so there is some noise. However it is not a problem, especcially when you close the shutters at night. The appartment is on the 5th floor and there is an elevator. There are 2 metro stops very close and we took a walk to the Sagrada in about 20 minutes. Many shops and bakery also within alking distance.
The balcony is rather small and you should not be afraid of heights to go and have your breakfase there..
