The following notes are based on my preferences and may not be issues that concern you. I do not book air bnb flats to save money but to live like a local when I visit a city. I don't expect four star hotel room perfection but I do have certain expectations which I do not consider unreasonable. I booked this apartment based primarily on the glowing reviews so clearly there are those who love this place regardless.
First the pros:
The location is excellent and easy to get to. We chose to transit by taxi (25€ at 4p weekday) since we wanted to see the city. The neighborhood is quiet at night and bustling during the day and is very close to cafes and shopping. The Rambla and major sites are an easy walk. Late night grocery shopping is literally across the street. Yvonne is very communicative and typically responds quickly. This review is in no way intended to harm nor tarnish the reputation of the owner but simply provide information which more accurately describes this apartment.
Now the cons:
yes there are 3 windows but they let in zero light and open to very close walls of next door buildings. The apartment is pitch black even on sunniest days requiring turning on all the lights to simulate sunlight. No fresh air and no views.
'Courtyard' is very inaccurate and deceptive. It's simply a tiny space between buildings that's filthy and not something you want to look at.
The 2nd 'bedroom' is a converted closet and extremely claustrophobic.
To use the toilet you must sit at an angle since it is inches away from the shower.
Overall, although nicely appointed with quality fixtures and decor, the apartment is very uncomfortable for anything other than sleeping, which if you don't set an alarm you will do quite well since the sun is completely blocked and will not help you wake. In my opinion these shortcomings should be noted in the description since they are significant and very much affect the experience. So much so that we cancelled the last three nights of our seven day booking and relocated in part because there were construction workers with a jackhammer and saw starting at 830am each morning. In the end Yvonne was agreeable to refunding a portion of the three nights but defended her listing stating it was not in violation of air bnb standards.
