Nice apartment and up to the expectations. The location is good. It is in a quit residential area, with plenty of restaurants and shops around, yet not far from the main touristic attractions but getting to them will require to use public transportation.
Ewa is really a welcoming host, all arrangements were followed and communication was perfect.
As a minor issue, I can only mention absence of a dishwasher in, otherwise, fully equipped kitchen (even a Nespresso coffee machine was there!)
More serious shortcoming, however, was the boiler that was definitely not working as it should.
Otherwise, it was a great place to stay in Barcelona
