A perfect stay in Barcelona!
My partner and I stayed in Arama's apartment for the last two weeks of July. Everything was excellent!
The apartment is exactly as shown in the pictures, though it feels bigger when you're there. The location is excellent, being near everything you may want to do in Barcelona, but far enough from the crowds. There are two metro lines very close to the apartment and buses that take you anywhere you want (we loved the 16 bus to get to the beach of Mar Bella). You can also walk to the center of the city (1 km, less than a mile), to Montjuïc (800 m, 1/2 mile) and many other places. We even walked home from Park Güell (a 5-km- or 3-mile stretch from the apartment). The neighborhood of Sant Antoni is very nice, there are a lot of shops, supermarkets and restaurants near everywhere.
The apartment was very comfortable, the washing machine was perfect for us due to the longer stay, the wifi works perfectly (the password must certainly become an internal joke for everyone who has stayed there, it's really long, lol), the air conditioner cools the whole apartment. We had read a small number of people commenting on noise, we had no problems whatsoever. It's good to know that the bedroom is in the middle of the apartment, so even if people would be talking in front of the building, we never heard anything.
If I had to be picky, the one and only thing I would change would be the shower's height (it stand at about my chest to belly (I'm 1,75 m or 5'9''), but it's easily manageable because the shower is not fixed on the wall).
Also, I suggest putting another trash can to make it easier to separate the recyclables and a smaller one for the organic stuff.
Arama was super friendly and made herself available for everything we would need (which we didn't, since it was all 100% great). She has a lot of suggestions for a nice trip to Barcelona too.
I definitely recommend staying there.
