the pictures simply cannot do the view justice, nor can the coziness of the hosts. The home is a mix of colour, chaos, and heart. Ulvi is a great host and made us feel welcomed immediately. he was a bit busy on occasion, but my girlfriend and I love exploring cities without much guidance, so that wasn't an issue.
The place isn't the cleanest in the world, so if that's a big concern for you, i might suggest you consider another place.
if you want the greatest, warmest, and most spectacular welcome to Istanbul though, it's perfect.
