To make it clear right away: it wasn't worth the money. I'm aware that Amsterdam is expensive, but it was too much for what we got. Heleen is a Superhost on Airbnb, so we formed our expectations accordingly.
Pros: Heleen was really friendly and helpful. She left, beside the basics, coffee, tea and two reusable water bottles (she explained to us she and her husband are trying to use less plastic, which we found really good).
We had a hair dryer, additional blankets, coffee mugs, plates, etc.
The bedroom and the bathroom were quite clean. The bedroom carpet was kinda dirty though.
The check-in/out were really easy.
The location is quite fine, the public transportation is easily available (trams 13 and 19 are 2-3 minutes away, tram 17 is 6-7 minutes away). There are also a supermarket, a bakery, etc in walking distance.
Cons: We had no locks on the bedroom and bathroom! Coming from a culture where privacy and private space are highly appreciated, this was an absolute no-go. We didn't feel at all comfortable leaving our things there, or taking a shower. On our first day we came back in the afternoon and there we found a guy in our room, sitting on our window! Turns out, it was Heleen's husband who painted the windows on the outside. She did send me a message on Airbnb half an hour before we came back, but I'm not looking at my phone the whole day, so I didn't see it. We were shocked. The worst thing is, we booked the room in April, so they had plenty of time to do the painting. Also, she didn't ask if it was okay for him to do it, she just informed us. They did apologise and all, but that was a huge breach of privacy, which I don't have any understanding for.
There was no heating in the bathroom. Taking a shower was quite a challenge (it was mid-October).
They were really loud when walking up and down the stairs, or generally walking through the appartment, the talking was also loud. We were out almost the whole time, but it started before 7 a.m. and didn't stop before 11 p.m. We weren't partying so we went to bed quite early and wanted to sleep a bit longer ('cause hey, vacation), but it the noise was really disturbing. I understand that it's private appartment and all, but if you wann host people, you have to adapt as well.
To sum up, if you expect Superhost quality, you will be disappointed. The price/perfomance ration is skewed.
