This apartment is ideally located for a young family (we had a three year old) as it’s less than a 10 minute walk to the beach. There’s plenty of space and there’s plenty of shops and restaurants close by. The Metro is only a 10 minute walk away and you can be in the centre of Barcelona within 10-15 mins. Most Metro stations are also very pram/push chair friendly.
The apartment is well appointed and has everything you could want during your stay. Pau (the host) is also super helpful and responsive to any queries you may have. Would definitely recommend!
