Karen's flat is perfectly located in Astoria, only 20 minutes away from cenral Manhattan (N-train), the subway station is only a short walk. The neighbourhood is quiet and safe, nearby are many nice cafés and restaurants.
Check-in was easy and perfect, communication was very fast and everything worked as planned. The room is small but it's enough space for two people and two suitcases. It could have been a bit cleaner, though. Another disadavantage was that the flat is badly soundproofed, so if you are a light sleeper and if the people in the other rooms are not very sensitive, you'll need ear plugs as you will hear evertyhing from the kitchen next door and the bathroom down the hallway.
Still, we would stay here again. It's best value for money and Karen was a great host. Thank you very much indeed.
