We really enjoyed our stay at John's place! The studio apartment had everything we needed for 5 days and 4 nights in the city. John met us for check-in and was very courteous. He provided food in the fridge for us! This was not expected at all, and covered most of what we wanted for breakfasts and snacks. He had all the information we wanted about local spots to check out, etc. The apartment is comfortable and quiet. It is on the back of the building so there is really no street noise, even with the window open. Because it is on the top floor we heard no neighbors overhead. The building is very quiet, we hardly heard another soul the whole time. The AC unit was quite adequate for the time we used it when it got hot.
The neighborhood was great! We never felt any issues with safety, even late at night. It was nice to be in a "real" neighborhood and not surrounded by only yuppies and tourists (like us.) There are more upscale restaurants, cafes, bars in the area too. The subway is very close and it's easy to get to other areas of the city quickly, that way.
