We had one night in Bari and this place was very convenient - it's on the edge of the old town, so perfect for exploring, but also only a 15 minute walk to Bari Central station. Check-in and check-out was all done via WhatsApp but it was all very easy and straight-forward. They also very kindly let me leave my luggage in the communal space after check-out as my flight wasn't until the evening.
