We had a lovely three night stay. The location is great and you can walk to all the key attractions. Some great local restaurants and we highly recommend the Secret Deli which is a short walk away. Rosa's brother was also great and we felt like we had our own tour guide.
We had missed our flight getting to Barcelona and also lost our luggage, Rosa was incredibly helpful in rearranging our pickup and access to the apartment. She also checked in over the next 48 hours till our luggage arrived.
We would definitely stay again.
