It's further to St Pancras than I thought it would be, and ironically closer to London Euston. However, they're all relatively close to begin with so there's not much of a difference in terms of distance. It's near many grocery and convenience shops so that really isn't a problem. There are also a few halal restaurants and butchers in the area so food is quite accessible, even for Muslims. The basement flat is directly below a Turkish restaurant that also serves halal food so that's a plus in my book.
However, I find it to be slightly inconvenient for heavy luggage travellers as the stairs down to the basement room is quite narrow and the walk from the station is twice as long when carrying heavy luggage. The shower place is also a bit unusual for us as we have never had to sit down and use a hand shower to take a bath before. We were used to standing up to shower so bathing become a bit messy. The walls are pretty thin so you can hear the restaurant upstairs as well as the train moving throughout the day and some parts of the night. If you aren't too sensitive by noise like me, this shouldn't be a problem.
Other than that, we were really pleased with the place. Complete amenities, including a dishwasher, microwave, washing machine and oven, it was like a second home. La's also quick in responding on her Airbnb account so it was quite convenient to receive guidance on certain things and fix certain issues (like not knowing how to adjust the heater properly etc). All in all, we enjoyed our stay and would definitely come again.
