A renovated apartment with a funky layout in a very old building. Great location in the Alfama, safe and close to nice restaurants, nightlife and the Santa Apolonia train station.
Good and bad on the WiFi, the bad is that it is very slow. The good is that it is a cellular connection, so you can bring the cellular router with you for WiFi access, at least until the battery dies.
Hope that at least one of your days is bright and sunny and you have 20 minutes to rest and relax: their balcony is every bit as nice as is shown in the picture.
