Gea's place is very simple to locate and is in an amazing location, with only a 10-15 minute walk to the train station and a 10 minute walk to Dam Square if that, so it is very easy to access from the centre. The air bnb was one of the nicest places I have ever stayed and it was very clean, the electric bed was the best thing about the place I did not want to leave! Gea is very welcoming and lovely, she was very flexible about the check in and out times as she let my friend and I drop our bags off in the morning as we got an early flight so we could explore Amsterdam with no hassle. There was also a bottle of wine waiting for us upon arrival! If you are looking to spend a couple of days in Amsterdam I cannot recommend her b&b enough, if I ever return to the city, without a doubt this will be the first place I will go!
