Eleonora's flat could easily be summarized with one word: terrace. Multiple words: green terrace facing a green park in Gracia! :) The terrace and the neighborhood can easily hold you captive and you won't be visiting anything in Barcelona.
The flat is located in the Placa del Nord, a very cute and green park, in the very vivid neighborhood of Gracia. Easy access to metro/busses and a big supermarket Condis Life is a great plus. The building is new and has an elevator, which is great in general, but especially for having babies and strollers. The flat was properly equipped with the basics and we really liked having the extras for our baby: highchair, bathtub and crib.
The biggest downside with the flat is that it has too much useless furniture that take valuable space for travelers. We were 2 adults and one baby and we already had issues with space. I also doubt that the flat has 80 sqm without including the 18 sqm terrace, so maybe it's more accurate to say that you have ~60 sqm of liveable space inside, for 3 rooms, a bathroom and a kitchen. I myself cannot imagine 6 people living there but that's another story.
Regardless, we have truly enjoyed our stay there, and we would gladly stay there again. It is a gorgeous terrace, no doubt - make no mistake you do not rent a flat, you rent a terrace! :)
