Karen was very nice, she let me check in a bit earlier than I was supposed to, was great in terms of pointers for the city and transportation, and very understanding in terms of my schedule (I used to wake up very early). The bathroom was very clean along with the kitchen. The rooms are filled with all kinds of stuff, but I enjoyed it since it really added to the entourage and gave a great Brooklyn vibe. She is also a great cook and provides you with all kinds of breakfast deliciousness and jams. The location is perfect, 5 min from Union St (R train), you can get anywhere from there and the neighbourhood is safe.
The only thing to keep in mind is that the loft itself is on the second floor (a ladder leads there, which may be tricky for some people) and it is an open area with no actual doors. Didn’t bother me at all, but just a heads up since it may be important for some.
