Stayed here with my wife and 8 month son and this flat is perfect for us. It was so good for my son to have his own room with everything he needed and the apartment itself has everything you need to make food and relax after a long day of exploringing London.
The apartment is perfectly placed between Dalston, Stoke Newington and Newington Green with a nice park right infront of it. We used to live in London and didn't need to go to central, there are so many good pubs and cafes close by as well as grocery stores for all you need to stay like a local. The overground and buses are near by when you do need to travel further.
Cass is a great host and super responsive on whatsapp to set up the check in and out, I didn't need to message them for any issues as we had none. The bed is comfy, the shower is good, the kitchen is fully equipped with great coffee. I couldn't recommend this enough if you are travelling with a young child or if you just want to stay in a cool flat in a cool part of London.
