We stayed one night and would like to have stayed longer. The panoramic suite was lovely, with great views over the city. Michele was friendly and helpful, organising a taxi for us and giving us his recommendations for restaurants. Recommended.

I stayed at Residenza Kastrum for a week, and I'm so very glad I did. Comfortable, clean, quiet, well-located (you could almost throw a stone and hit the cathedral) -- it was everything I could have wanted. AC kept me cool, Wi-Fi kept me connected, and my continental breakfast on the pleasant rooftop terrace was a wonderful way to start the day. Michele were helpful and attentive, and tolerant of my broken Italian (though he speaks perfectly good English). I hope to come back again soon!

We stayed three nights at the Kastrum in August 2010 with our 4 years son. The rooms are set in a renewed old house in the historical center of Cagliari. Bit difficult to reach if you have a big car, but charming as all the old town centers in Italy!
The room was big and well organized, bath with shower very clean. Stunning view over the whole gulf from the roof small terrace, where breakfast can be taken.
Michele welcomed us with very useful hints on the town and the surroundings: best beaches, restaurants...and also offered a sunshade for our day on the seaside.
WiFi was available and functioning pretty well, which is not common in B&B in Italy!. Just one unique remark on the breakfast, a bit too much "industrial".
Definitely a place we would like to come back to!

Stayed in the Panoramic suite for 4 days of a 7 day stay & we were blown away at the standard of accommodation. Michele was a discreet but perfect host even delivering an umbrella to our room on a day that rain was expected!! The terrace was a delight with fabulous views. The breakfast was simple and a new coffee machine has certainly answered previous criticism!! For the physically able RK is ideal for a truly local experience... Be sure to listen to Michele's restaurant recommendations, he knows what he is talking about!! We will definitely be returning and taking friends to stay in the adjoining Panoramic room.
