The cab driver did not have any issue finding the flat's location which is always a good start when you arrive from overseas :), the drive was 30 minutes from the airport. The reception with Isidre was perfect. Kind attentions from Isidre included refreshments in the refrigerator, coffee and various spices for cooking. The apartment was clean and the kitchen well equipped for people that like to cook their own meals. The location of Isidre's flat is perfect with a 15 minutes walk to the Sagrada Familia and 30 minutes from the Barcelona Cathedral. Within a 10-minute walk of the flat, you will also find very good restaurants, multiple fruits stores and groceries. The only issue we had was with the climatisation units' water pumps, they start and stop every 1 or 2 minutes when the units are on, I am a light sleeper and even with ear plugs I struggled to find deep sleep.
