Unfortunately there were many difficulties during our stay.
Communication:
It all started one day before we arrived, when we were moved to another flat, because the shower in the other apartment was ostensible defect.
That circumstance would have been okay for us, if the communication from Alcambarcelona had not been that bad:
Some of their staff always texted us in spanish, did not react after several calls and gave us different information about when we could enter the apartment. I would also like to point out to other airbnb users that a very high tourist tax (which seemed higher than the official one) was due after booking.
The apartment:
As described in the communication paragraph we were moved to another apartment (it was called Gold Big - you can se it on the official website of Alcambarcelona).
The appartment was very smelly even after intensive airing. We've also found several living cockroaches, that were as tall as my fingers.
The kitchen was clean, but the promised basic kitchen equipment was missing. Speaking of missing, there was also no hairdryer and a part of the cooker did not work.
The interior was more than spartan and did not invite to stay longer than necessary in the apartment:
The dirty wall should be hidden by picture frames without any pictures. The sofa was also very uncomfortable. And like I mentioned early - it stank very badly.
To be fair, though, I have to mention that apart from the noisy street, the flat is very well located. A metro station can be reached in 2 minutes and other buses that go to many attractions can be very quickly reached as well.
In addition, the electronic door lock was very useful as it allowed us (unfortunately only after we had to ask several times) to move around more flexibly and agilely in our group.
Overall, our experience with Alcambarcelona was not good. The flat was different from what was described, the communication was poor and unprofessional.
I think they are well aware of the deficiencies as they easily refunded us 120€ for 7 days after we complained.
