We stayed in Alexios's apartment for 5 nights and had an amazing time.
Alexios is the perfect host - he's attentative, he offered us plenty of tipps for our stay on Serifos, communicates fast, clear and responsive. He made our stay a blast!
And that with the increased challenge to do it all from afar, since a very happy happening - good luck with that! -prevented him from being on Serifos in person.
Check-In and -Out went flawlessly.
Alexios even managed to organize a ride to the ferry port for us when no taxis driver was available. Again, he's simply the best!
The apartment is small but very homey, floodlit and offers everything one could need.
It was very clean, towels, shower accessories and a bunch of basics for cooking/breakfast (salt, pepper, olive oil, sugar, coffee, paper towels and so on - all the little things one doesn't want to buy for just a couple of days) were available.
It has a little front porch and a huge terrace on the back, so you can always find a hiding spot from the intense sunshine if needed.
The location of the apartment is also really good - in walking distance from the main road of Livadi with all it's restaurants and shops (but far enough not to get disturbed by loud music or partying folks) and even closer to the Livadi beach (pack your sunscreen, not a lot of shade there...which we liked :-D).
We decided to rent a boat and discover some of the hidden bays of Serifos, definitely recommend doing that. Alexios can give you advice as to what provider to choose and even offer a small discount for it - we learned that after the fact, so you don't have to make the same mistake we did. ;-)
Our time on Serifos was great and we wholeheartedly recommend staying at Alexios's lovely apartment!
