The good: the location is Gracia is great. The views are lovely, and it's fun to stay in a residential Spanish neighborhood. The wifi and washer/dryer worked well.
The not-so-good: we struggled to sleep due to poorly functioning air conditioning (the AC near the bed didn't cool the room, and it made loud, frequent noises all night long). The bed is not very comfortable, and covered in a poorly-fitting plastic mattress protector. Only two thin, flat pillows were provided for the bed. Overall, the apartment furnishings are very sparse and minimal. Check-in: communication was a little challenging and I wasn't aware that I would need to instill What'sApp to communicate regarding our arrival. I wish I had known that in advance. The listing stated that we would need to have exact change in cash to pay the tourist tax, and went out of our way to get exact change in Euros, but when we arrived the person checking us in told us that she preferred credit card and cash was unnecessary.
