The flat is in a great location, is clean, modern and well set up with everyone you need for a short stay.
The downside of the location is that it's quite noisy at night - but we knew Shoreditch High Street would be noisy, so this wasn't a big surprise for us.
The only downside of the apartment is that there is no a/c or fan and during our stay it was SUPER HOT! Especially in the mornings - the apartment has lovely windows and great light, but faces east and gets blasted by the sun on a hot summer morning.
We had a few problems with check-in - whereby we were not given all three keys we needed (apparently no one realised the people who rented the apartment before us hadn't returned all three keys before the incomplete set was given to us). Which resulted in us getting locked out at 1am by a security door which had been open when we first checked in. Luckily a neighbour let us in, and we were able to pick up the key we needed from the cafe the next day, so it was not a huge problem.
Overall, the flat was good value for money and we had a pleasant experience and I'd stay here again - although I'd probably check that the weather is going to be cooler first.
