Great apartment, absolutely as described- possibly even better! It is a really great space. There is a large kitchen, perfect for cooking and a large table for eating (or playing a board game). There is a handy balcony too, if the roof terrace isn't your thing (or if it is raining).
Lotte was a great host, very communicative and very responsive. The apartment is very easy to find, no. 13 tram straight from Centraal to Mercator. The apartment has lots of maps and guides etc. so that is advantage if you are new to the city. The location of the apartment is excellent too, perfect for a quiet weekend. Not suitable for nightowls (as you are in a residential area) for sure, but there is a supermarket right outside the front door, as well as coffee shops and nice cafes. Cook Cafe, or De School are particular favourites just round the corner, but the always excellent Starting at Jacob is just 15mins walk.
I would definitely recommend if you are planning a relaxed trip, as it has great transport access to Centraal, the Jordaan and De Pijp, while also being right in the middle of several beautiful parks if you just want to relax in the neighbourhood and feel like a local.
