Many thanks to the Unique Family for our stay in Barcelona!
In general it was good but unfortunately with a few shortcomings. First of all would like to say that the check in was perfect. The location of the apartment is also great if you choose to live near the Sagrada Familia, there are also several lovely cafes and restaurants in the surroundings, a supermarket etc.
weak points: we stayed 5 people in the apartment, and we had not enough soup simply to wash hands; it was also little bit noisy because of the lift in the house due to lack of noise-isolation in the rooms which are closer to the door and the hall; the apartment was darker than we expected: two bedrooms without windows, so you have to use lights always, at the day time too
