First off, Jackie and Alice were wonderful hosts! They were able to accommodate my stay on short notice and were very proactive about communicating with me during the process.
This apartment was a wonderful place to stay, especially if you're planning on spending most of your time out sightseeing/visiting. It is an "internal" unit, so all of the windows open onto a hallway (they're all frosted glass to maintain privacy). There are two windows that can be opened securely if you want to leave them open at night.
The benefit of this type of unit is that you're shielded from the considerable noise outside. The unit is spacious, and there's an air conditioner, so it never feels stuffy.
There's a gas range in the unit so you can make coffee or tea in the morning; Jackie and Alice are very generous about having coffee, water/soda, and snacks available for you.
One feature that really made the difference for me is that the apartment has a secure key-carded front entrance with a doorman. The door to the apartment itself only has a lock on the handle, and a chain, there's no deadbolt. Still, I felt secure in the unit, the building feels very safe.
One last thing: the sheets! Seriously, they are unbelievably soft. It was hard to get out of bed in the morning.
I highly recommend this apartment
