The flat is exactly as described, you can see (but not hear!) the subway moving in and out of the station from the front window, and leave the back window open for fresh air. The living room is spacious, has a desk suitable for working, two comfortable sofas and a table sitting four. The kitchen has all the basic equipment you need, including a manual espresso maker.
This is a neat and tidy flat for business travellers and as an exploration base for the city alike.
The hosts were very helpful, showed me around and responded to messages quickly. When wifi went down, Michael did everything in his power to bring it back quickly.
