We felt in love with Menorca. It is a lovely place with awesome beaches, good gastronomy and rich culture and traditions.
Damian's place is well located, close to the airport and Mahon where you can find restaurants, shops and all you need. Close to the apartments there is a local supermarket with all the basics for your stay although this is a bit expensive.I would recommend to go to Mahon where there are cheaper places such as Mercadona, Eroski, etc.
The apartment is well equipped with all the amenities you may need. Don't expect nothing fancy or luxury, everything is very basic but enough. We used to spend most of the day out, but sometimes we were in and cooked our meals for the following day.
Regarding Damiá's attention, I just have good works for him. First day we asked for 2 new pair of towels because the ones we had didn't look so good and he almost immediately brought them to us. We also contacted him by whatsapp almost every day to ask him about places to go, good restaurants, etc , and he always replied to us. He also provided us with umbrella and chair to use at the beach! As a local, he knows everything about the island therefore his recommendations were always right!
I would definitely recommend Damia's place to someone who wants to visit Menorca.
