Very large and well organized apartments.
We were a group of 9 girls , visiting Lisbon for a Bachelorette party. The apartment had space for all of us including also enough bathrooms for every girl's need:)
Communication was always effective through whatsapp, including self check-in details, further infos over the areas (including restaurants etc).
Only thing to point out (which is anyway highlighted in the apt annoucement) is that the apartment is on the 4th floor without elevator, but this is very common in the city center houses, so just something to note down in case you're coming with kids/strolleys etc.
Definitely I would recommend for large families, group of friends etc ;)
