Renting at Maria's flat was very nice. It was our second airbnb in Barcelona and it was very convenient as the area is very dynamic with a lot of shops. The only thing was we thought it was someone's flat but it is a professional company, you can also find the flat on Booking so maybe if there is no availability for one flat you can switch and find another one. The check-in was easy, we paid taxes for the stay, it was clean. We just noticed one bad smell on the bathroom but it disappeared the next day. The terrace is very convenient and I think a big plus during summer. The flat's location is very convenient, next to a L1 station, next to Montjuïc and Plaça de Espanya. Thanks for your kindness and all the tips given.
