We were a family of 5 (3 teenagers) and Alfredo's worked very well for us. There was enough space for us all to spread out in relative comfort and the slightly quirky decor was appreciated by our teenagers. The ceilings were high to give you an additional feeling of space.
The location was excellent, we found it very quiet and in very easy walking distance to 4-5 subway lines.
Alfredo provided quick and detailed responses to our few questions. My only suggestion would be to include a compendium of information on local services, supermarkets (etc) and on how to use the home technology. All this information was provided in a timely manner by Alfredo but it having it at hand would have enabled us to use it as a reference, possibly initiated ideas, and would have allowed us to get by without disturbing our host unnecessarily.
