I stayed here one night on a very cold day, so it was not as nice as in summer but still liked it very much. I find the negative reviews very strange.
I am a discerning traveler, having stayed in many real top class 5-star hotels, but had absolutely no complaints about this hotel whatsoever. I paid only 50 Euro and got a BIG room for that, room 312, an invalid room with big bathroom with shower, room L-shaped, 7 meters long and wide, with balcony facing a beautiful view. It's not very private but so what? One hears the traffic on the nearby roads but still a great view. Indoor swimming pool is wonderful and a sauna. Only drawback is when children play in that pool. Free internet in the lobby (when children are not playing games on it). Good restaurants, great breakfast. The building the rooms are in looks very modern and not outdated at all. Personell VERY nice and polite and helpful. My room was very quiet, no disturbances at all.
No airco, so in summer it might be hot. TV in that room is big enough and could turn towards bed or the sitting area. 30 channels, incl. BBC 1, 2, CNN. If you have a choice ask for rooms 309-316 as these have a balcony and facing the nice view (others on other side face the parking lot).
I will surely come back some time in warmer weather.
From Dieren (2 km away) is the start of 2 wonderful walks. Descriptions in Dutch on the station.
To reach Avegoor by public transport, take bus 43 from Dieren station, direction Arnhem. Get off at stop "Avegoor", just 3 minutes from Dieren.

Stayed in this hotel as part of a Gift for Two voucher I got via work. The website looks very promising and an excellent get away for a romantic weekend. However it turned out to be different - upon arrival the only room available was a room with two single beds. The room itself was not up to four star standard: uncomfortable (single) beds, no bath, room was, shower was weak, room was cold upon arrival as was the hotel. It is a strange mix of four star prices with a two star look and feel. The decor is depressing at best as somebody has decided to paint the halway ash gray. Food is tastes nice but extremely expensive. 15 grams of steak on a big plate: 27 euro!

Really avoid this hotel. it is not worth it.

I stayed here before.
If you read the reviews: I share the critical onces.
They do not give you what they promise.
A 'modern' white room is awful outdated and dirty (after complaining they said they are busy with renewals).
Food is good though. Restaurant chairs were really broken!
Staff is quite young (cheap?) and not always professional/right attitude for such a hotel.
Nice swimmingpool.

My wife booked this as a luxury break for my 40th birthday. She picked the place from the website which presents it as a luxury hotel. Be warned: it is not.

Our surcharge designroom with 'private' balcony looked ok and was clean but certainly no design. The furniture is ikea style. Nothing wrong with it but nothing special either.

The balcony made us laugh. It's very unattractive - see our picture. And not private at all.

We rented a tennis coach ourselves to teach us tennis basics but the tenniscourt was not maintained. It was slippery and full of leaves and in fact rather dangerous. This suprised us because my wife called beforehand about our plans to get tennis lessons there.

The main building is indeed nice but when you expect a design hotel the 80s sidebuilding that houses the rooms is a rather depressing sight.

All in all we had an ok time but would most recommend d a couple looking for a romantic break to look elsewhere. Leave this mediocre place for business meetings.
