Jerónimo and Catalina's place is an absolutely fantastic base to explore Barcelona from, and I had a lovely stay! They're very friendly hosts, happy to answer questions and give useful local knowledge and tips, and very quick to respond to any queries.
The location is perfect - less than a ten minute walk to La Sagrada Familia and the surrounding area, and very well connected with transport, with many buses and metro lines within connecting distance. It's also very easy to get to from the airport so that's a positive too!
The apartment is exactly as listed with all amenities mentioned available. The bed was very comfortable for me, as I travelled solo I can't speak for the sofa bed but the sofa itself is also comfy so I'd imagine it's the same in bed form! The coffee machine in the kitchen was a very very welcome treat - 9/10 times the listed coffee machine at airbnbs doesn't function properly, but this one does. It was lovely to sit on the small balcony with a cup of coffee (or three!) in the mornings, even in early November when the temperature starts to fall a bit. The shower is very easy to use and works perfectly, no fiddling with dials trying to get the perfect temperature!
Overall I had a fantastic stay in Barcelona at this apartment, and hopefully it will be available for me the next time I'm in Barna. Thanks Jerónimo and Catalina!!
