I stayed at Maria Louiza's place for a quick weekend getaway. It was exactly what I was looking for since my intention was to spend as little time indoors as possible and enjoy the outdoors as much as I could. The only caveat is that the room is a bit small BUT, it has been renovated recently and it feels like a BRAND NEW construciton, the decorator has done an amazing job all around (choice of colors, fixtures, lighting, outlet placement etc) which help the room punch way above its weight.
Wi-Fi is fast, room was spotless and smelled fresh, communication with Maria Louisa was effortless. I didn't really need to communicate with her as much since I didn't really have any issues but she was just a phonecall or text message away every time I reached out for her.
Location wise (if you want to stay at Batsi), you can't really do better. Even though the veranda offers just a partial view of the water, the room is just a few steps away from the main road from which u can hit the 2 nearby beaches by walking 150 meters in either direction. It is just a 10 minute drive from the island's port and it is within walking distance (just shy of 5 km if you enjoy walking that is) from 3 of the island's most popular beaches. There is a municipal parking space nearby (under 500 meters) in case you have a car, where you can park safely while in Batsi.
I can definitely recommend the place for a quick getaway, or even for longer periods of time, provided that you will spend most of your days explonring the island and using the room mainly for sleeping and recharging your batteries.
If you are looking for a place to throw a party at, this is not it. If you are looking for prime location, an attentive host, a clean and tidy place, a working shower and toilet in MINT condition (more of a rarity than you would think), then look no further. I 've been visiting Andros almost every year for the past 102 years or so. I'll try and stay at Maria Louiza's place again if available.
