Stayed at Arena for one night with my boyfriend before journeying to Rotterdam. Both of us had a great nights sleep only disrupted by some loud banging at 08:00 am, at which point we should have probably been awake already.
Easy enough to get to by tube/metro (Weesperplein) or tram (7 and 10 stop very close) and is walk-able from Amsterdam Central in 40+mins. The hotel is situated on the corner of Oosterpark which has some interesting art work and sculptures dotted about. This is a fairly quite area but in easy reach or the more lively city districts.
The hotel, a renovated orphanage, is fairly unique with huge granite staircases and tall ceilings which lend well to the split-level rooms. A lovely mix of old and modern.
The breakfast was good and reasonably priced. We didn't use the restaurant or the bar as we wanted to explore the city a bit.
Would definitely come back.
