I have a lot of mixed experiences with this AirBnB, so I'll list them in positives and negatives.
-- No wifi. This was by far the biggest issue, as I had to completely change how I operated during Zagreb in order to get around, plan trips, occupy my time at the AirBnB, contact relatives, etc. The room is advertised to have wifi, and honestly, I wouldn't have gone with it if I had known it wouldn't, because I don't have mobile data. So if I wanted to do anything online, I had to go to the city centre and linger outside some restaurant, and use their free wifi instead.
- They brought people around on the second night without mentioning it. Of course, it's their home, they can do as they please, but if you're hosting someone, please tell them that there will be other guests.
- I was moved from my planned accommodation to a separate building, a ten minute walk further from the centre (though the difference by tram was negligible). This did not cause much of a problem for me, but it should be noted.
- The hosts smoke indoors. I didn't mention this at the time because I didn't want to be rude, but future guests who have issues with smoke should be aware of it.
- The door to the bathroom does not close, as the top hinges are broken, which meant that I couldn't use the room privately unless I was alone in the flat.
++ The ladies are all very friendly and helpful. They happily give directions and came to pick me up from the bus station when I arrived in Zagreb.
+ The flat was clean and well decorated inside.
+ I had access to good facilities for cooking and cleaning.
+ The bed is very comfortable. It was a double bed, rather than the single bed advertised, so that's also a plus.
I would absolutely love to give this a five star review, and recommend it to others, but I can't. However, the problems I had are really easily resolved, so other guests might not experience them in future. Wifi is easy enough to get, and I think the door to the bathroom could be fixed without much trouble. The smoking indoors and bringing around guests are things which can also easily be stopped temporarily while hosting. I wish these ladies the best, and I'm sorry I could't be more positive, because they really are the most lovely people.
