I stayed at the Park Hotel in Amsterdam, and in my opinion it is a very good hotel, and normally I stay in 4* or 5* hotels so I know what standards to expect from a 4* hotel.
To be honest we were put in the Park Hotel by accident because of a booking error but I'm quite glad we did because we had a great time. Amsterdam is a brilliant, quirky, and unique city and Stadthouderskade, where the hotel is located is right near Vondelpark, and also the museum quarter. It's well away from the red light district and is on the nice side of Amsterdam. It's right near one of the canals and you can hop on a canal barge more or less right outside your hotel! The views of the canal are fantastic, but you have to be careful to try and get a canal view because at the back of the hotel all you can see is buildings. Contrary to what was said in another review, the beds aren't any lower than other beds in hotels and the rooms are cosy and attractive and the fact that there are tea and coffee making facilities is absolutely brilliant! The best thing about the hotel is it's breakfasts (there's everything!) and it has a warm and friendly atmosphere. In fact Mrs Warboys off One Foot In The Grave was staying in the hotel at the same time as us (so it can't be bad if somebody off the TV is staying there!) And trust me, it isn't... if you choose to go to Amsterdam, the Dutch people are amazingly friendly and so are the hotel staff! It's the best hotel in a city location that I've stayed in!
