I stayed in the Love and Rose houseboats in July and had a fantastic stay, and I am already dreaming of coming back... The boats are really close to Centraal Station, but far enough from traffic that it is really peaceful and relaxed. I'm glad we decided to stay somewhere central, as it was really easy to get everywhere on foot. The Nieuwemarkt area is lovely, we bought some delicious food from the Saturday farmers market. There's also a supermarket, bars, the Cotton Club jazz, and Chinatown (lots of restaraunts and takeaways) less than 10 minutes away. We loved the independence and homely feeling from staying in a private boat.
The Love boat was amazing, full of character, and much bigger that it seemed from the photographs. I notice that a previous reviewer didn't like the boat- but we had no complaints. It certainly was not dirty, and nothing was "sticky." It didn't have any bad smells, or smokiness. The boat toilet is fine, it really isn't a big deal. We had no issues with noise, or being woken up by other people walking in the boat, and I know the gentlemen on the boat next to us were out on the town till the early morning (we know becuase we chatted to them over a beer on deck!).
Also it is clearly not a bad area!! None of the owner's boats are rusty, maybe the nearby boats had a bit of rust, but nothing like a trailer park- I thought it was a nice area. It is easy enough to check the area on Google street view, which we did before we arrived. We were sent information on absolutely everything before we arrived, so we knew exactly how to get there and what to expect (the boats are exactly as shown in the many pictures). Nina showed us around, and was lovely.
Our stay on the Rose boat was also fantastic- but I felt I had to defend Love as we loved it so much! 10/10
