Mustafa was a great host, he was always easy to contact - and even spoke to our cab driver, helping to direct him from the airport. He met us at the flat and gave us a map and helped to orient us in the city. The place is more like a little hotel, there is always someone down in the lobby and there is a housekeeping service. It is a two minute walk to Taksim Square, and there are lots of places to eat and drink nearby. You can walk down to the Old Town tourist centre near Aya Sofya in about 45 minutes, but the public transport is very easy to use, and will cut that journey down to 20 minutes. It's definitely more fun to stay in Beyoglu than in the Old Town. The internet worked well. There is a hob if you want to cook. There is a 24 hour grocery around the corner. This apartment is great value and I would recommend it to anyone.
