This is a nice place up in the hills overlooking Barcelona. For me, the price was higher than I typically spend on Airbnb, but it was completely worth it. The views alone are amazing and provide a completely different, zoomed out perspective of the city.
Maria is a friendly host and was very flexible with checking in/out. The room was comfortable and clean. Note that the access to the room requires climbing stairs and the entry into the room may be difficult for someone with mobility issues. The room has all the basics that you would need, including an air conditioner (didn't need to use thanks to the sea breeze) and large refrigerator.
For a couple looking for a place in Barcelona, this is an easy choice. Overall, if I could live in this place - I would.
