Stayed in this apartment with my wife for 9 nights
The good:
Location is great, Rooftop is wonderful, Communication with host is good.
The bad:
The apartment is dirty and smells, there are cracks in the walls, sofa is covered in gross stains, air conditioner ( the only way to warm the apartment) is making loud noises which is a problem at night. Water pressure in shower is very bad. When we first walked in the apartment my wife had to ask the host to clean the floors because they were dirty. We spotted some bread crumbs on the sofa, the reply from the host was " I don't know, need to speak with cleaning lady". Apartment smelled like cigarettes. Shower doors are broken. Door to bathroom will not stay closed (which might be a problem). Tiles in the kitchen are broken, tiles in the shower are broken.
There is no way to attach pictures to this review, so if interested to see how this glamorous apartment looks without edited photos, I have put a short video , just enter this code in search engine vEq6UUMq9dg and you will find the video Apartment Review Gran Via de les Corts Catalanes 701
I think for this price a host can be bothered to keep the apartment clean and well maintained
