Overall we had a good time at Casa Ma Li and we would recommend staying there - if the missing air conditioning is not an issue for you.
Below a few more details.
On the plus side:
• great location: close walking distance to archeological museum, Sansevero, spaccanapoli, Spanish quarter, metro (100m), supermarket (50m)
• amazing high ceilings. This makes you feel like you are in a castle, back home felt like being trapped in a cage in comparison.
• reasonably well stocked kitchen (microwave missing)
• clean
• Fabrizio is a great host: He met us and showed us through the flat, the fridge was stocked with some beer, yoghurt and juice; he gave us helpful tips for the local area, helped arrange a good value cab for the airport, was great in dealing with some challenges (for instance when our smallest started colouring the walls)
What could be improved:
• No air-conditioning!!! (Lots of fans are provided but they don't really cool the room down enough). Fabrizio was able to address this by providing nearby alternative accommodation which had air conditioning. Thanks again for this!!
• a few small bits were missing: microwave, shower gel/shampoo holder, some electricity wall plugs didn't work
Thanks again Fabrizio for being a great host!
