During the construction phase, a conscious effort was made to use natural and sustainable materials. Natural stone, crafted by a small local company, was used for countertops, shower areas, and sinks in the kitchens and bathrooms. Durability and regional sourcing were also prioritized for the wood, which came from a local supplier. Much of the furnishings were not purchased new but rather found at secondhand markets or acquired from other guesthouses. Furthermore, Harm crafted many pieces of furniture himself from wood, including beds, patio tables, and the bar.

There are olive, lemon, fig, almond, and carob trees on the grounds. Last year, they produced their own olive oil for the first time. The carob trees are harvested, and the fruit is delivered to a local farmer, while the other fruits are used for their own processing. Plans are in place to further develop this area, including planting additional fruit trees and creating a vegetable garden that could also be available to guests. No food is wasted: leftover produce is either given to cleaning staff or to other guests.

The hosts collaborate with local gardeners, cleaners, and construction workers. While there are no special conditions, good working conditions are ensured, with fair wages and often additional benefits. For example, guests frequently leave behind food and drinks, which the cleaners greatly appreciate and put to good use, thus preventing resource waste. Furthermore, the hosts support Casa do Povo in Moncarapacho – a "House of the People" association active in social services, education, sports, leisure, and culture. Donations are made, and the hosts also attend Portuguese language courses there.

All accommodations are well insulated and fitted with double glazing, helping them stay pleasantly cool in summer and comfortably warm in winter. For added comfort, underfloor heating is powered by a combination of solar thermal energy and a heat pump. This energy-efficient system creates a comfortable indoor climate while using significantly less energy than conventional heating systems. The energy supply is designed to generate as much energy as possible on-site, minimize waste, and maximize self-sufficiency. With 27 solar panels, they produce a large share of their own electricity. By using most of the energy during the day, the best use of this renewable power is made. Excess electricity is stored in a 14.3 kWh home battery, allowing them to use their own solar energy even when the sun isn't shining. Sustainability extends beyond the accommodations. The hosts are committed to protecting the environment and preserving nature for future generations. For many years, their family has financially supported Greenpeace, contributing to the protection of biodiversity and efforts to tackle the climate crisis.

Yoga sessions and massages can be booked on-site, performed by external professionals who come directly to the guests. Harm himself also organizes wine tastings featuring Portuguese wines. Furthermore, the area offers many sporting activities such as hiking, stand-up paddleboarding, cycling, surfing, and boat trips. A particular highlight of the region is the Ria Formosa, a nature park located just five minutes away and considered one of the most beautiful natural areas in the region.
