We arrived before our check in time and were very tired after our journey . We asked if we could check in early prior to our arrival and Iban was very accommodating and was waiting for us with the key to the apartment.
The apt is in a terrific spot, only five minutes walk to the Metro and Sagrada Familia. The apt is spacious and very clean. It was quite cold for our first 3 days but we had instant heat at the touch of a button which was great.
There are lots of restaurants, cafes, bars , supermarkets and shops all on your doorstep.
A great place to stay in Barcelona and we would highly recommend staying here.
The only negative i would have is , the kitchen is quite small if you were cooking for a few. We ate out every evening so it was not a problem for us.
