The flat had all the basics that my girlfriend and I needed for our 4 night stay. It was quiet, the bed was comfy and the holiday guidebooks were handy. The location was brilliant: it was a minute away from the metro and a short walk to Sants train station. The local bars and restaurants were also nice, and there were local supermarkets nearby. We particularly liked the square around the corner from the flat (Plaça d'Osca).
Marta met us upon arrival, was very friendly and spoke great English. She was prompt in her responses on Airbnb and WhatsApp, and also provided helpful recommendations. We appreciated her help and would definitely stay again if we visit Barcelona again!
