I had a great experience at the Singel Hotel.
The staff is professional, kind, and cares about you.
The reception is open 24h, and they are always ready for you.
I arrived after 11 p.m, and they gave me advice, tips and information to have a good time in the city.
The hotel is less than 10 minutes walk from the central train station, and the interior is cosy and fancy.
I liked my room, well cleaned and with a comfortable bed.
The breakfast is super, and there is the sweetest lady that attends to you.
I RECOMMEND IT!
