Booking and establishing contact were super easy and painless. We communicated via email and Sonia replied without delay. Check-in/out procedure was quick and welcoming. Sonia's boyfriend David greeted us and gave access to the apartment - even provided us some bread and coffee. Apartment itself was fantastic. Everything matched the pictures posted and clean. Place was not dusty at all and looked well-maintained. Great WiFi connection, clean kitchen and washroom, comfortable bed, etc. Feels like home. Safe neighbourhood, and safe building too. Elevator is large enough for 4~6 people. Washroom is a bit small, but it is very clean and you can wash yourself without any problem. - unless you are very overweight or over 2m tall. I consider location as one of the most important factor when I choose my place through Airbnb, and Sonia's place has excellent location. 3min walk from Arc de Triumph metro station, and it is connected to everywhere. Barcelona has great metro system(with cool A/C!) that will give you access to almost all tourist attraction. I will go back to Sonia's place any time. 9.9/10 - 0.1 deduction because I found that hot water tank is bit small. After my girlfriend washed the water became cold (not ice cold but slightly lower than body temperature). But girls use lots of water and take their time when they wash so it should not be a big issue.
