We spent two weeks at Meritxell's place and we felt like at home. The apartment location can't be better, in one of the local 'historical' neighborhoods of the city where you can experience what is like to live in this city. In less than 5 minutes walk from the apartment you will find so many cool bars and restaurants that your problem will be to decide which one to try. There are also a number of supermarkets of all sizes within minutes walk, as well as public transport including a metro stop in less than 10 minutes walk. And then, you have the beach, as well within 10 minutes walk.
As we were visiting family outside the city we had a car (what you don't need if you just visit the city). There's no free street parking around the apartment, but there was always plenty of it by the beach at the end of La Rambla del Poblenou and we never had any issues finding a spot.
The apartment itself is like shown in the pictures and has all you need to cook. At our arrival we even found different options for breakfast, what we really appreciated. The WiFi connection was super high speed and never let us down, what was very important for us as we were working and needed to be able to have concurrent video conferences.
It was January and cold, so we didn't use the terrace which is in the upper floor, separated from the apartment, but with better weather it must be awesome.
