Our stay at Daniel's place was very nice. We were there in late December/early January and found the heat to be more than sufficient. We found it was best to run the heat in the morning and then turn it off well before bed as the basement bedroom was always quite warm.
For us the location was very good because we had another part of our group staying at the Generator. We also found catching a cab (we used cabify and recommend it) was easier from in front of the Generator also as the street the house is on is very tight.
I would recommend that you bring eye masks and ear plugs if you are a light sleeper. Even though the place is off the main street it was still occasionally very loud as the windows offered little sound absorption and the street lights are always on. We were in the middle unit of the three townhomes and we could hear our neighbors throughout the night.
Extra blankets and towels would have been nice. There is a very small washing machine in the unit, but no dryer so doing laundry in January was a bit interesting.
Sergi, the rental manager, was very helpful and attentive to any questions that came up and made the process from start to finish very easy.
