The good:
The space is right in the center of Shoreditch, you couldn't ask for a better location if you're into the nightlife (Nightjar, Callooh Callay, Happiness Forgets, Found)... and some entertaining dive bars (Cirque, Looking Glass, Cargo). It's also 10 seconds away from Brown (a strip bar).
There's a Tesco Express a few blocks down the street for groceries, and plenty of ethnic fast food open late at night.
The apartment itself is a studio (not really a loft), but we loved the attention to detail when it came to lighting. That may sound strange, but the lights were placed well and added some ambiance to the space. Also enjoyed the large windows and view over the street. The noise didn't bother us at all, even on the weekends.
The not so good:
We both enjoy a hot bath after walking all day. You'll need to turn the faucet all the way to the right (hot) and let it run completely out (takes about 1/3 of tub), then the water runs cold until it reaches the right temperature. There isn't much hot water - so you have to get it right the first time. Also, it takes awhile to get hot again - so we ended up staggering our baths. Me at night and her in the morning.
The 'cabin' looks great in photos, in reality it's cramped, a small bed (just a futon) with no space to walk around the sides. another half meter on either side would have made all the difference. Also a shelf or two to place things on once inside (a drink, cellphone etc). The cabin is a nice idea as a design element, but functionally wasn't that fun to sleep in.
The amenities could use an upgrade. The two towels we got were pretty basic, as was the 1/4 bottle of 'African' shower gel and inexpensive coconut shampoo. A nice set of 'hotel' amenities would have been welcome. Likewise; nicer pillows, a better comforter on the bed (and a real mattress would have gone a long way. A throw blanket on the couch would have been nice too. The internet was touch and go. At the low end sometimes we only got 2.9mb down. Other times we got 16mb. YMMV.
Conclusion:
If you're just looking for location, this is a great stay. The host was ALWAYS responsive and you'll be in the heart of nightlife. If you're looking for something upscale or romantic - not so much. The small details turned what could have been an excellent week long stay into one we were ready to move on from. At this price point you expect a little more finish. But again - it's the location.
