This was a private studio on the ground floor in Garcia, about 5-10 minute walk from the metro. My girlfriend and I stayed here for 3 nights during our Barcelona visit and have some positive and negative reviews about the space:

Pros:
-Studio was in a nice and safe neighborhood
-Federico was very helpful and accommodating (offering early check-in, ride to the Airport and provided travel information/suggestions around the area)
-Communication for arrangements was quick prior to our stay
-Studio was spacious and fairly accurately described as per listing

Cons:
-Hot water was an issue for the two of us, short showers were necessary
-Bathroom had some foul smell which we mitigated through the constant use of air freshener
-The double bed was actually a sofa bed and was not very comfortable
-Bedsheets and pillow cases appeared to be quite worn and unappealing, we ended up buying our own set at a local store
-Wifi signal is weak and only available near the back end of the studio
-Sometimes loud during the night as the studio is located on the ground floor
