James was a great host, very responsive to my questions. The flat had a few things I just wanted to point out to future guests. First, the water filter was not there during my stay, but I believe they are waiting on back-ordered filters so it should be there for future guests. Second, the first time I used the oven the fire alarm briefly went off and my food was not even cooked. I ended up running the stove fan even when baking in the oven and it never happened again. Third, the heat in the winter doesn't seem to reach temperature you set it to, but this didn't bother me much because I like layers and blankets. I also did not mention the 2nd and 3rd points to James, so not his fault.
The flat is great for business travel, since it is small but has everything. The place is comfy. The added perk of the rooftop, I sadly did not get to enjoy, because of cold/rain/snow, but I did check it out briefly and feel like it would be great for morning coffee/tea and evening wine/beer.
