If you arrive at Melaka by Bus at Melaka Sentral, a public bus to the Discovery Cafe is only RM 1,50. The location is more than great, because all the main roads are pretty close to the guesthouse. Also the river is very nice - there are a lot of cafés and it's just beautiful to walk along it at night.
I also liked the guesthouse itself, because it's very clean, the beds are comfortable and of course Allan, a staff member, helps you with everything you need that you can enjoy your stay! He's such a nice and interesting person, he's one one of the reasons why I enjoyed my stay in Melaka so much :)
