We were looking for a place in Milos to few months ahead and chose Manos place because of the scenic photos of the place and the price. It was not as pricey as the rest of the options. Manos and Eva met us at port upon arrival and took us to the place which was very convenient since we were tired from ferry trip. We got the white room 1 and we can't say we liked it. The room is really small and has one tiny window. We felt uncomfortable. We called it "a fridge" - not because it was cold inside, but because we felt like we were inside an actual fridge. Once you're inside, you're also "isolated" from the outside world since you have absolutely no connection - no 4g and no wifi signal. The bathroom is really small with low ceiling and the shower is inconvenient without any curtain -- if you want to wash your head without splashing water all around the bathroom, it would really come of as a challenge. The common area, however, is really nice. If you don't plan to stay inside your room too much, you might be fine.
We were also willing to rent an ATV, but had some luggage so we decided to go with Manos and Eva suggestion to rent an ATV directly from them. This sounded great since we wouldn't be able to rent it somewhere in the port upon arrival with the luggage and everything. We were given an ATV for 75 EUR per day and were assured that the ATV is really good and "very strong". The ATV, however, was very rustic and old. Driving it was a nightmare. Eva did offer us an option to give it up and take something else at port, but at that point we were lazy to make a switch. Anyhow, if you're planning to rent an ATV, we would suggest checking options and the pricing elsewhere before renting.
The weather in Milos got really bad during our stay and we decided to leave Milos earlier. Manos and Eva took us to port earlier without questions asked and returned some money for unused ATV days.
All in all, it's a scenic place with stunning sunsets but the living itself wasn't comfortable for us.
