Our stay with Loni mostly followed the positive experiences of other AirbNb reviewers. The location is great! Apartment is cozy, very well equipped and accurately described. Loni's greeting and orientation to the area and Barcelona was helpful and appreciated.
During our short stay we encountered a problem that I have learned is common, and this year particularly bad, in the Barcelonetta district. Cock roaches. Big ones. Not many, one or two per night, but enough to be very unsettling. When advised Lori was appreciative and sympathetic but as the stay was ending not much could be done about it for us.
Nevertheless, on balance, our stay was good with just enough "local reality" to make it feel authentic.
