Pros:
*Location, very close to Sants station and several metro stops.
*Cleanliness. It was noticeable because upon arrival everything looked and smell clean.
*WiFi
*Check-in is super easy vía a link. BUT make sure you have internet connection!
*Host’s responsiveness.
*Has an elevator, which is not the rule in big cities.
Cons:
*Although the apartment is not expensive for rental, a basic maintenance is always welcome.
I would definitely come back.
