It´s a very nice apartment in a nice neighbourhood of Graça. It is very clean and modern just as shown on the pictures. You will love the place.
Problems:
1) The owners delegated it´s management to a very unprofessional company. Communication works badly. Owners don't communicate with you personally, so when you think you exchange messages with Filipe or Barbara, actually you are chatting with somebody who works for the company that manages the place. Be ready for having to wait for reaction to your messages for a day or two. And when you do get in touch, every time you have to deal with a different person, who has no idea what your previous communications were about.
2) The apartment is underpowered, so if you try to use air-conditioning and a microwave at the same time, power in the whole house goes down. Electric tea maker and washing machine turned on at the same time does the same thing.
3) Internet is slow. It is ok for facebook and email, but if you need to Skype somebody, forget video-call function. I needed to work on-line a lot, so that was annoying. If you are on a holiday, speed can be enough I guess.
