Miguel's apartament is really cozy and spacious for big 8-persons family. We stayed for 7 nights and everything was okay. Two bathrooms are helpful, as well as private bedroom for every pair. The living room is a great place to spend time with whole family. The kitchen is adapted to cook normally. However, because it's huge apartament, it can be cold during the night, but Miguel provides a lot of blankets and heaters.
It's nearby metro station, so there is no problem in getting to apartament. There is Continente, Mini Preco and Lidl in neighborhood. If you wanna rent a car, you have two companies closely.
I really recommend this flat for longer trips.
