First of all Gert is a great host, and good person. Very easy to talk with and flexible.
The apartment is exactly the same you see in the pictures, it is clean and spacious. I think this is extremely good for the people staying most of the day exploring the city, and then enjoying the breakfast and dinner in the apartment.
Although I think the apartment is more suitable for the young people. It has everything to enjoy the company there.
There is a nice balcony, and I believe in spring and summer this is the nice place to have the breakfast outside.
The location is great, at least we were looking specifically for this area, as there are lots of children playgrounds, park and small open farm/zoo near by, where you can see rabbits, pigs, chickens, ponys, goats, and sheeps.
Also if you have your sport shoes with you, you can enjoy running in the park where lots of people excercise.
Although there is one thing which is not Gert's fault or the apartment's pitfall, currently there is the reconstruction in the neighbor block, and it is very noisy between 9am and 6pm. But if you spend most of the time outside, that should not be the problem, but in our case with the baby it was a problem.
But this was resolved by Gert at time by offering to stay in his sister's apartment instead. Which was even the better place. Which again proves how great Gert as the host.
Also there were the toys our baby liked which is great!
So, I believe as soon as the reconstruction in the neighbor's block is done, I would then definitely recommend Gert's apartment to stay in and explore the Amsterdam!
