This place has an absolutely fantastic location right in the heart of Amsterdam. It feels very private as well--the bedroom and bathroom are separated from the rest of the apartment, so it's like having a small apartment all to yourself!
Check-in was extremely easy, and Andy was extremely generous about letting me leave my luggage in the hall before/after my check-in time.
People with a lot of luggage should be aware that the stairs are quite steep, but nothing unmanageable. The mattress was not the most comfortable I have ever slept on, but overall this is an excellent place to stay if you want to be right in the middle of things!
