Gan is really a friendly girl. When you arrive, she takes time to explain where we are on a city map and how to move through the city. She also makes recommendations about interesting places to visit, restaurants where you can eat spanish food (at low price), bars, etc. During your stay, she pays attention that you get everything you need and she is very open to discuss.
The appartement is very well located in a street perpendicular to La Rambla, consequently it is located in a lively district but not noisy (in March for sure). There is also the subway near the appartement, and a bus to go directly to the airport.
House is clean. You can use the kitchen and the living room as yours.
I really recommend to stay with Gan!
