We had a good stay at Loft 2. The location is fantastic and the apartment is very spacious with lots of natural light. There was milk, tea, coffee and some sweets on arrival (no crumpets/bread, though, as advertised). We did, unfortunately, encounter some downsides. Branca was my initial contact and lovely to deal with, but someone else took over before check-in and was not pleasant at all. He was abrupt and terse, demanding I get in contact thirty minutes before arrival (Heathrow Airport is a 60+ minute journey by train) even though I had not planned on buying a SIM card and the apartment was advertised as a self check-in. He also didn't bother to reply to a message I sent about how to work the home entertainment system. The neighbour, Kyle, who let us in the apartment was nice and friendly, and was very accommodating with us arriving late because our flight was delayed by an hour. Like I said, though, this wouldn't have been a problem if it was actually a self check-in, as advertised.
The street noise is pretty constant, so keep this in mind if you're a particularly light sleeper. That being said, we didn't mind it and found the constant bustle added to the charm of the neighbourhood. It was fantastic having Brick Lane market on our doorstep as well as a multitude of restaurants.
There was damp on the walls and it leaked in places when it rained. That didn't bother us, but it's worth checking with Branca whether it's fixed if you have severe asthma or allergies and are concerned about it.
We had trouble with the two smoke alarms in the apartment. The one positioned directly outside the bathroom would go off every time we opened the bathroom door after a hot shower. The one in the kitchen was set off when we opened the oven door just after preheating it. Not a huge issue, but it was quite annoying and unsafe to constantly have to deactivate them for periods of time and then reinstate them again and again and again.
I would recommend still recommend staying here, but perhaps ask Branca about any of the minor issues we encountered if they may cause you some concern.
