I had just relocated to Amsterdam from the US days after the city went into lockdown and Agnesa's place was the perfect place to hunker down at as I was still in the process of searching for housing. Check-in was extremely fast and Aniko, who lives downstairs, was very helpful in getting everything set up. Everyone was away for the holidays but I had everything I needed: a place to cook simple meals, fast Wifi, hot water with good pressure, plentiful blankets and towels. The Chromecast was a nice addition and I was even able to receive takeout food/packages downstairs quite easily. A huge bonus was being able to laundry during the lockdown.
The location itself can't be beat being near to both De Pijp and Oost and a block away from the Metro to get into Centraal. I would assume that post-lockdown, this spot is even better since you're by the scenic canal, parks, and a good number of restaurants so that you won't have to rely on the supermarket (though Albert Heijn is literally around the corner).
Agnesa and Christina themselves were very easy to reach and extremely hospitable. For those looking for a medium-term place to stay and/or have been to Amsterdam before and want something a just slightly outside Centraal, this place can't be beat.
