Although I didn't actually meet llana (as she was away herself), she was very helpful through messages and would always reply quickly. She was also very friendly and provided lots of good advice on things to do/where to go in the centre and the area local to the flat.
The place itself is very clean and well presented and has everything you need for a long weekend away. It is only one room and be aware that the shower opens straight into the room. This wasn't a problem really, just for people to be aware! It was a good size, the bed was very comfortable and me and my boyfriend would definitely go back!
The location is a good 40 minute walk or so into the centre but we loved this as it is a good way to explore and see the city. If you don't want to walk then it's not a problem as there are great public transport links via tram, bus and train. The area around the flat was awesome too, there are some lovely restaurants that llana will tell you about. Definitely try Walter Woodbury's and the Thai Tiger!
Overall, a very pleasant trip and great place to stay. I will be sure to stay again when I return to Amsterdam! :)
