We've also been to the blue Cottage as well before, both are decorated with love, super clean and comfortable. They are in the backyard so it's private and quiet. The close entry to the big parque de Cidade is also a big plus.
I couldn't say which apartment I liked more, I think the bathroom in the blue cottage is nicer but I liked the room itself and the balcony in the green cottage more.
Constança answered always quickly if we had any questions, check in was easy and flexible. So all in all we highly recommend both of her cottages!
