We booked and stayed at Rocío's apartment for 5 nights in September after reading all the positive reviews. We will try to highlight all the pros and cons during our stay here.
Pros: Firstly, the location is great. It is situated right next to a metro station (Rocafort) and within walkable distances (20-30 min) to La Boqueria Market, Magic Fountain, Las Ramblas, etc. Check-in was fine, but you will need to be able to call a different individual so make sure that you have access to cellular services. There were some problems that required fixing during our stay and they were addressed (also see below).
Areas of improvement: Honestly, this was an older building than we expected and a little dated. Noise was an issue both within and outside of the building because the sounds echo and reverberate (especially the loud slamming of the doors/gate) and there was construction occurring next door. As mentioned in another review, the fluorescent light from the building interior filters into one of the bedrooms and the thin curtain does not help much so the bedroom remains quite bright throughout the night. In addition, the mattresses in that bedroom were quite uncomfortable, as you can feel the springs protruding into your back. We had to move one of the mattresses from the other bedroom over (luckily we only had 3 in our group). Would recommend earplugs and an eye mask if you sleep in that room. In addition, would be great if better care of the apartment was exercised before guests were checked in. For example, we had to ask for more necessities (soap and toilet paper) and some of the lightbulbs in the bathroom/bedroom were not functioning. The microwave is missing the glass plate and the washing machine is extremely old and does not work properly (we regret using it, but had no choice because we were expecting to do some laundry here). Air conditioning unit works fine but was old and is only available in the living room so the problematic bedroom can be warmer than the rest.
Overall, it was an okay stay. We have stayed in many airBnBs prior to this and, given the above, we may have opted to pay a little extra for a more comfortable stay
