We had a really nice time at Amsterdam, thanks to Katja and her mom who were here to help us. Katja's mom accepted to let us check in a bit earlier because it was raining really hard that day. They are really lovely people.
About the studio itself, it was really clean, with eveything we could need on a daily basis. The location was great, no big noise, very beautiful and calm. The subway and night bus (along with a supermarket) were really close by, it was easy to go around and visit the city. We were recommanded to visit Pijp, and so we did, lovely neighborhood even at night !
Check in and check out were really easy, Katja even made a little book to explain little things like how to use her expresso machine.
Thank you again !
