This was way more perfectly situated than I could’ve imagined - a 10 minute walk from Plaça d’Espanya for the aerobus (direct from the airport), 5 minute walk to several great museums, 15 minute walk to some of our favorite restaurants, and 5 minute walk to the Poble Sec subway stop. There were also a few buses that were very convenient and accessible. Most places were about a 30 min ride away maximum, and we were able to walk to half the things we wanted to see.
Communication-wise, Luis was great at checking in with us and giving us information (found out about the Aerobus thanks to him). Lucas met us at the Airbnb and showed us everything, and check-out was very easy (just leaving the keys inside).
The apartment was perfect for our needs; there was quick & plentiful hot water, an iron, good wifi (a little better in the living room than in the bedroom), towels, an expandable table that folded out well for board games, hangers, shampoo, and bar soap. I personally don’t use bar soap but I brought my own liquid soap and toothpaste. The apartment was clean and decorated tastefully. It was a good stay for the two of us, and I would likely stay here again to sleep on the sofa bed if I brought my parents.
