I stayed in Cristofer's place for five weeks and I fully recommend it for either short or long stays. The apartment is small but has everything you need: a really comfortable bed (which is really a rarity on AirBnB), fully equipped kitchen, space for remote work -- all very tastefully decorated and in great condition. The location is excellent: quiet but well-connected to other busier areas of the city. The beautiful park belt of north Buenos Aires is within walking distance. Cristofer himself was very helpful and kind, and I hope to be able to stay in his place on my next visit!
