While there were A LOT of positive things, from the location to the hospitality to the kindness of our host to the low price, there were a couple small things that impacted our stay in a big way:
1. THE BIGGEST PROBLEM: This unit and the one next to it used to be one apartment, and then a thin wall was erected between them so that they could be two apartments. This wall is paper thin, meaning you could hear the conversations that the people in the other apartment are having. The first two nights, our toddler and our tendency to stay out until 10PM every night was very inconvenient to the couple staying in the other apartment. For the rest of the stay, after that couple left, a family with kids moved into the apartment and they would be very loud and playful, often until midnight. Needless to say, we could not sleep :(
Another side problem, not the fault of the owner, really: this unit shares a main front door with another unit (they were both one apartment and a thin wall was put up between them)... the neighbors we had would never lock the front door! So we felt very unsafe with that door being left unlocked when they'd come home at midnight. Also that front door is very heavy and has to be SLAMMED shut in order to lock it properly (that's why they never locked it, they weren't told how to use the door). This means that when the neighbors come and go, you and all of your guests are going to be awaken.
2. The internet was very poor, it was almost non-existent.
3. Apartment was not exactly like listing: no adapters for non-220V devices, no complimentary tea basket, the cutlery and plates were not like the ones in the picture, they were very low quality.
Overall, if both apartments are rented to people with no kids, and both groups have similar come-and-go times, the above is a non-issue, but that's not something in our control, and not something we were aware of going in.
