Sonder positively surprised me! I wasn’t expecting much from the low price (for Amsterdam), pictures and bad Google reviews, but our stay was great! We arrived late after a long travel and were greeted by the employee at the desk with a tin of stroopwafels. The room was very well equipped and looked recently refurbished. Location was perfect, right by Vonderpark and just a few minutes away from Museumplein. Within 30 min walking you can get to pretty much any attraction in Amsterdam.
My only complaint is about pre-checkin communication which was unpleasant. I had to create a Sonder account and received several “URGENT” emails saying there was something wrong with my reservation. I would confirm through Airbnb chat thay everything was okay and then receive another email. I would prefer that all communication be carried out through Airbnb.
My last remark is not necessarily a complaint, just a suggestion. It would have been nice if Sonder could store our luggage after checkout, which they said they could not. It didn’t get in our way, but since there is 24/7 reception, I don’t see why not.
