Our family of 8 had a wonderful time in this apartment! It was sparkling clean, appeared as advertised, and we were very comfortable. The host who met us, Flor, was very helpful and available by text/email. The location on Avenida del Parallel is great for subway/bus access, taxis, and distance to the most popular attractions of Barcelona. It was the perfect choice for us and we are happy we stayed there.
Here a few things of which you should be aware:
1. There is no electric dryer. There is only a clothesline.
2. The elevator is very temperamental. You should never have more than 2 people in the elevator. EVER. If you have luggage, maybe only one person. We followed these instructions, but two people in our party got stuck in the elevator for about 20min. Someone was able to quickly come and fix it, but it is tricky and cannot handle much weight at all. Other tourist groups have broken the elevator in the past and the local residents are frustrated by it-- so try not to break it!
3. The residents of the building are not happy that tourists are staying there. I did my research and this apartment appears to be legally registered as a tourist apartment with the city of Barcelona, so I believe that everything is in order, but your neighbors will not be friendly to you. In fact, they will be a bit hostile. Several people gave us an earful about how it's "illegal" and were pretty upset. As paying visitors to the property, you cannot do anything about the residents' feelings, but be aware that you might encounter disdain.
Despite these few issues, we had a lovely time in Barcelona and were overall happy with this AirBnB property. We recommend it, especially for larger groups. Thank you, Victor and Flor!
