At £98 (115€) per room, this deal from Amsterdam's 4-star Hotel Arena saves a massive 62% on the usual rate and includes overnight accommodation in an upgraded Studio room, breakfast (worth 18.50€ per person) and a welcome drink in the hotel bar.
As well as a restaurant where you can sample a 3-course surprise menu and the ToDrink bar, the hotel has an on-site club (set in the chapel of a deconsecrated church) that's open on Friday and Saturday nights. There's also a large terrace for alfresco snacks and drinks. Studios are larger than the standard rooms and most have high ceilings and original features. All rooms at the hotel are individually designed.
The hotel is a 10-minute tram ride from Centraal Station or a 15-20 minute walk from the city centre and is a few blocks from Hortus Botanical, Amsterdam's botanical gardens. Oosterpark -- home to Amsterdam's Root Festival of global music from 4-7 July -- is also very close.
Valid seven days a week from 4 June-28 August. A minimum 2-night stay applies. A city tax of 5.5% is not included in these rates and is payable locally.
Travelzoo tip: Do as the Dutch do and explore the city by bike. The hotel offers bicycle rental from 16€ per day.
