I've stayed at the hotel for two nights and as for such a stay it was perfect placed in the center within a walking distance to Ann Frank's house or Amsterdam Centraal.
The low price was an additional plus of the property as well as the building itself, which is very nice to an eye.
For some, lack of the lift might be an issue, as the staircase is very high with a lot of steps, but that is typical in Amsterdam's old buildings. For me it was an additional charm.
I've stayed in a room on the last floor (more steps = better workout ;)). It was small, but comfortable with a great city view and balcony to enjoy the city from. Small, but well designed bathroom was just enough for my needs. There was a safe in my room, so I could store my valuable items as well.

Breakfast was very nice, could be enjoyed on a terrace with a city view :)

Overall, I am very pleased with my stay at DiAnn.

I feel very thankful to get a room at Hotel Di-Ann for my stay in Amsterdam when I was there alone as a tourist. I had booked the room less than a week before my arrival at Amsterdam.

The staff of the Hotel are the people who help make my experience meaningful and positive despite the hotel having no lift and room furnishing is basic.

Hotel Di-Ann stood out because it met my requirements:
1) It was close to the heart of Amsterdam. It is about two tram stations from Amsterdam Centraal station. I could talk a 15-20 minutes stroll and reach Amsterdam Centraal station by foot.
2) It was relatively near many places of interest.
3) Free WIFI! I felt thankful that the WIFI is consistently working even in the room area.
4) Compared to other hotels in Amsterdam at the locations I was looking at, it was considered reasonable.

The staff at the hotel are friendly and helpful. This helps a lot. I am also thankful that the staff of the hotel would extend their service to help me book an airport shuttle to the airport on the date of my check-out. My request to have my luggage stored temporarily in the storage room was also very well attended to.

The room is very basic so please keep expectations manageable. I had a room for one person and it was a compact room with all the basic amenities fitted in.

The hotel does not have any lift. I understand this appear to be a common issue even for the nearby hotels in Amsterdam. I felt thankful that one of the hotel staff went the extra mile to help me take my luggage up the stairs upon my request for help. However, people who have issues going up or down the stairs may wish to consider other options as the stairs were relatively steep.

Breakfast was basic. If food runs out, ask for some refill.

I like the architecture of the building that the hotel is located in, and the best part of breakfast was to take a seat at the table at the balcony area and look at the view of the neighbourhood from the balcony. The only thing to watch out for is that other guests may smoke while they are at the balcony.

There is no safe in the room. Guests may enquire at the reception if they need a safe to store valuables.

A good location. So if the price works out, I am willing to consider. Afterall, I have had relatively good experience with the staff at the hotel who have been very kind to attend to my requests.

The neighbourhood is relatively safe. There was one night when I returned to the hotel around 2 a.m. Except for the fact that the traffic lights do not work at that hour, I felt relatively safe to walk back to the hotel from the nearby Dam area late at night.
