As a family of 4 we stayed at Joseps apartment for 4 nights in October.
It is in a great location with a bus stop outside the door and a metro line just 200m up the road.
The area is full of small restaurants and cafes offering good deals on eating out. If you prefer, which we did, to cook in house, then there is a fantastic supermarket almost opposite, and you'll find the apartment has all of the cooking facilities and utensils you need.
Josep has gone to a lot of trouble to create a guidebook on his AirBnb page, so be sure to look that up for activity and restaurant recommendations.
Josep was fantastic with his communication. He always responded in a positive, helpful and timely manner. Nothing was a problem.
We arrived by car and struggled to find the apartment using the link, not sure what went wrong there as the street is not down an alleyway and is easily accessible. Be aware that parking at the nearby underground car park wasnt cheap, so have a plan b if you need to park your car during your stay.
The apartment is lovely but it was smaller than the picture implied. 2 adults, one teen and a preteen ... we were on top of each other a bit, but fine for shorter term stay.
All in all a lovely stay. Loved Barcelona and we will be back.
