Nadia's apartment is well located in Sant Antoni, near a major transit stop, and the number 46 bus to the airport has a stop nearby. Be aware that this is not near the beach, it's about 30-45 mins away by public transport. The room itself is pretty nice, the walls are a little thin as is with most apartments in Barcelona. You get a private bathroom just for yourself which is very convenient, the shower is definitely small so be aware of that. The area is also super safe, even as a woman walking around alone at night. There are supermarkets close by and the apartment has a kitchen when you can cook, Nadia and her sister share it with you, including the fridge and cupboard space etc. The girls are really nice and welcoming, you have complete privacy and can come and go as you please, it also has a really nice and sunny balcony. Overall definitely recommend if you are staying for a few days!
