Staying in Andrea and Joanna's place was a great choice for our 3 days in Mdina! It is very central meaning that everything within Mdina is just a few minutes' walk away. The apartment has everything you need. Downstairs is the living room, kitchen, toilet and shower - all well equipped. There were even some spices we could use when making food! They also provided some bread and milk to get us started which is very handy when you just arrive late in the evening.
Upstairs are two rooms, one fitted as a living room and the other as a bedroom. The windows open onto the square looking directly towards the cathedral.
To get upstairs you use a narrow metal spiral staircase. For this reason, we left our large suitcase downstairs.
Remember that the electrical wall plugs are UK plugs. We found one adaptor in the apartment to use though, converting from EU to UK.
The church bells chimes every 15 minutes, but we got used to it.
Check in and check out was well organised and Joanna helped us with somewhere to leave our bags while we explored on the last day.
Highly recommended place to stay in Mdina!
