Kasey's place is modern, clean, very spacious (for 2 people), and comfortable. We stayed for 5 nights to as tourists and we had a great trip! Kasey was generally responsive, helpful, and friendly.
The location is decent for tourists, with some caveats. The area is safe. It's around 15 minutes walk to King's cross station or 15 minute's walk to Angel tube station, from which you can get anywhere you might want to go. There are nice bars and restaurants about 15 minute's walk away also. The downside is that walking those 15 minutes gets tiresome at the start and end of every day, especially when you are already doing so much walking during the day. The nearest large supermarket is around 15 minutes walk away, which makes buying groceries a bit annoying.
A few issues we had:
- The concierge couldn't find the right keys when we checked in so we couldn't get into the building for the first evening without the concierge - at one point we had to wait outside for a while before he returned to the desk
- For 2 of the 5 days we were unable to get any hot water in the apartment
- The bed was comfortable but only a double (not a queen) - I found it a bit small as I am 6'3
- There was no air conditioning and the bedroom got quite hot, so we had to sleep with the window open, and it was a bit noisy outside
- It's not a full time AirBnb but rather someone's home. It wasn't cluttered at all and we felt very welcome there. However, it was difficult to distinguish what we could use and what we couldn't. The freezer was filled with food and there were some items in the fridge. There were spices and oils in the kitchen, but we weren't sure if we could use them. We weren't sure if we could use the appliances in the kitchen cupboards. Also, there isn't a toaster.
Overall, this place is a good option if you're visiting as a tourist or for business, especially compared to a hotel or more expensive AirBnb.
