When booking at the Old Harbour Apertments, be awere that the front windows do not open. While i was renting the apartment the room was extremelly hot. Since the windows do not open we don't have a chance to let fresh air into the room. While these are nice apartments, be aware of this problem.

Family had the Roof Patio apartment. It is the top 3 floors (4th- 6th) of the building: Kitchen / living room area (also served as another bedroom for us) first, then up an amazingly narrow winding staircase to the first bedroom, bathroom, and roof patio. Up another narrow stairway to the A-frame second bedroom. Our first time in Amsterdam, so we weren't prepared for the apparently typical Dutch staircases. They are - no exaggeration - treacherous!
The good: Location. It is a 10-minute walk from Centraal Station and the Red Light district, but it was still far enough away that it was quiet at night. We walked everywhere from there.
The owner: He seemed truly apologetic for the construction noise (see below) and gave us a very small refund because of it, and he helped with the luggage up those stairs.
The bad:
there is SERIOUS construction going on in the basement of the house. The first jet-lagged morning, we were greeted with what sounded like jackhammers in the basement at 10 AM. After I complained, the owner got them to hold-off with the power tools until 11 AM, which we appreciated, but it tainted the rest of our stay.
The heat: they were inthe middle of a heat wave, with temps in the humid 90's, and there was no air-conditioning, just one lonely table fan. I understand that the temps were very unusual, but for what we were paying (200 E per night), there should be a couple more fans available, at least.
Those stairs: I'm serious, we were half-crawling up them.
Based on the previous glowing reviews, maybe our timing was off. I understand that Amsterdam hotel rooms are tiny and expensive in general, and we had plenty of room, a kitchen, dishwasher, washing machine, and a patio. The place is quaint, roomy for a family, has a good location. and is probably fine in normal weather, which is why I give it a tentative recommendation. All I can say is, make sure of the status of the contruction project before you book.

My husband, brother in law, and I stayed in the Roof Top Terrace Apartment July 3 - 10. The apartment is very spacious, clean, quiet and well equipped with everything you could possibly need. The location is superb. Close walking distance to Central Station and many other hot spots. The host was very gracious with helping us carry up our luggage up the steep staricases and making sure we had everything we needed. We will definately be returning to this gem of a location!

What more is there to say? The other reviewers have sold the virtues of these apartments and we totally agree. We stayed in the Guest room for 2 nights and the Patio Apartment for 3 nights and it was perfect for our working visit. The short walk from Central Station is very convenient and the facilities were fantastic. A short walk to cafes, restaurants and a supermarket; and a great place to base yourself when visiting the city sights.

I wouldn't recommend the Patio Apartment for the elderly or anyone with a physical disability - the stairs to the basement are steep and curved. The guestroom on the top floor is spacious, and has its own entrance. The toilet is located inside the owners apartment (but discretely set apart from their living area) - some people might find this a bit inconvenient. The owners were very obliging and carried our suitcases up and down the stairs. We'll definately be staying here again!
