Overall the apartment was a great place to stay. The private room is a self-contained room with separate bathroom and kitchen to the rest of the building. Easy access in and out of the front door as it is on the first floor (no stairs!). However, one set back we found staying on the bottom floor was the amount of stomping from tenants living upstairs. Probably not on purposes but very heavy footed. It would start around 6-7am and was literally continuous until lunchtime. (Don't expect to sleep in). Bathroom was cramped and the toilet flush was faulty causing it to constantly stay running. Washer AND dryer was available. No air con or fan (But room is very well insulated), stove top didn't work and TV didn't work but we were fine with that. The wifi also cut out and were left without internet for the last 4/5 days of our trip.
The apartment is in a great location for the size of Amsterdam city. Close walking distance to the station, Anne Frank house, Red Light District and tram stop. Most trams came frequently and didn't take too long to get to and from places. Walking would've been a killer.
Would recommend Mauro's place when staying in Amsterdam.
