Overall, we really enjoyed our stay at this flat. Great location (close to a major public transportation hub) and spectacular views, as advertised. The area is very charming, bustling with cafés, shops and restaurants.
People at Doormat were attentive and responsive.
We had minor quibbles about lack of certain items (like placemats in kitchen and towel holders in bathroom).
One slightly more serious complaint is that we onley received one set of keys. This is supposedly enough as there is meant to be a concierge 24/7. Actually, concierge is often away from from desk (I took photos) and, even if they were always there, a card is required to use the elevator. One card to go around our party of four was often not enough.
