This is a beautiful zen place to stay. It's only a 4 minute walk from Gjelina on the corner and numerous other fun places.
I'd say that if you like a very dark room to sleep, it would be good to have eye shades as both rooms are fairly light, although it's beautiful to wake up to the sunshine.
Whilst I was trying to sleep, the friend I stayed with was in the lounge chatting to a friend and it can be heard quite loudly throughout the apartment. So if you're a light sleeper, you may wish to have ear plugs if you have noisier guests.
I love to do yoga so I took a mat and enjoyed it on the patio every day.
Alex was a great host, he doesn't bother you but if you need assistance for anything he's always on hand and easily contactable. Lots of bits and pieces in the cupboards so you have the basics and a brita filter for fresh drinking water.
