Carla's place is fantastic. A clean and comfortable room with a nice view as well. Carla made us a fantastic breakfast each morning which local cheeses and breads. Its a 20 - 30 minute streetcar ride to Amsterdam Central and the stop is very close to the house. We got the multi-day public transport passes which were extremely convenient and well worth the money. Overall, if you plan on spending the entire day in Amsterdam, I would recommend. However, if you like to go back and forth between Amsterdam and the room very often, finding a place closer to the city would be better so you're not spending all your time on public transport.
