Jacqui's apartment is really stylish. It felt like being in a lovely shabby chic Paris apartment! The apartment is in an older building though so adjust your expectations.
The apartment is on the fourth floor and is accessed via a narrow flight of stairs. There is no lift. We only had one medium sized (25L) piece of luggage but any heavier would have been tough. Then again, lifting weights is good exercise :)
Both rooms face a major thoroughfare and the street noise can get quite intense, even with ear plugs. This was compounded by the roadworks being done during our stay.
We stayed in the small guest room which was only just big enough for us and our luggage. The main apartment is spacious though so we spread out over both areas.
The guestroom has a fan and heater but no air conditioning. Unfortunately this meant it was quite warm and stuffy during humid summer nights even with the window open (which let in more noise).
As noted by other travellers, the guestroom room is separate from the main apartment. Locking and unlocking doors (which creak loudly then slam shut) to get from one area to the next is a bit awkward. This which makes night time toilet visits inconvenient.
During our stay a nice family of four stayed in the main apartment. Six people sharing one bathroom is not ideal even where all parties are doing their best to keep the area clean. We also had different (but not unreasonable - we're a young couple visiting NYC on a weekend) sleeping times. We felt bad disturbing them when we had to enter the main apartment to use the bathroom, particularly as some of them were sleeping in the open space right outside the bathroom. People considering staying may therefore wish to check who your roommates are.
The location may look seedy but is actually quite safe. However, we didn't find much to do within walking distance.
Jacqui was out of town but communication and check in was, respectively, very quick and super smooth. Jacqui is a really nice person and did her best to make us feel as comfortable as possible.
Overall, our stay wasn't enjoyable but mostly because of factors outside of Jacqui's control.
