The apartment is great - exactly as described, very clean, comfortable, well equipped, sunny and spacious. In addition to that, it is unique with lots of antique furniture and details, fresh flowers and nice views both from the windows and from the rooftop terrace. The living room at times feels like a painting of Vermeer or de Hootch.
The shower is great and WiFi works well. The stairs are steep - both in the hallway and inside the apartment, but we got used to them quickly.
The location is also perfect. It is central, but quiet and feels safe. No touristic crowds, the supermarket is around the corner, tram stops around another corner. Tram line 24 goes straight from Ferdinand Bolstraat stop (130m from the apartment) to the city center and Centraal Station, lines 12 and 3 take you to Museumplein in 6 minutes.
The hosts Siem and Rianne made us feel very welcome. Communication and check-in/check-out was easy and smooth. We would love to book the same apartment next time in Amsterdam and will recommend it to our friends!
