This would be a great choice for a couple that wants a bit more space. Having two floors was a nice feature and made it feel bigger. The flat has all the basic necessities for a stay, and having access to in-flat laundry was a plus. Generally a clean, IKEA-style apartment. The location is very close to the Camden Town Tube station and buses were super convenient as well. Sainsbury and coffee shops, restaurants and pubs all nearby. While the area is lively, the space was pretty quiet. This is a garden apartment - so bedroom windows on the main floor facing the street, and the bottom floor below ground with good windows. Generally felt safe, but didn't leave bedroom window open at night.
There is enough sleeping space for 4 people (1 bed (queen size US standards), 1 pull out sofa (double size US standards). I wouldn't recommend the sofa-bed for extended stays if you are looking for comfort. It would be fine for a short stay.
Communication was ok - generally had to be initiated by us to get instructions (check-in/check-out, address, etc)
No house manual available but everything was there, and check in and check out was pretty easy.
