Really cool apartment. Just as described, got a cool vibe to it. in a great central location. Hosts very helpful, good communication.
One thing is you can't leave bags if you arrive pre-check in at 3pm, and the lockers at the nearest train station can get full so be aware if you have an early flight. There is also building work going on bang opposite but once windows are closed it doesn't make that much noise. These didn't affect our stay, just thought I'd point out for more sensitive travellers.
Overall a good spot, good base to explore Lisboa.
