I would rank Nicolet's Thekloofapartmemts as my #1 place to stay in Amsterdam.
The location is brilliant. The apartment is clean, new, spacious, minimilist & very comfortable. The beds are very comfy. The shower is strong & refreshing. The kitchen is well equipped. Smokers should not be put off by Nicolets "No Smoking" policy as you can smoke, drink coffee & chillout on the public benches opposite the house overlooking the canal & the busy Cafe De Jaren terrace - an excelllent Amsterdam experience. Finally, the warm welcome with cold beers gets two thumbs ups. Will be back for sure.
