The location of the apartment is very good with convenient transportation such as tram 12E and tram 28. The castle is right next to the apartment. The flea market is also at a walking distance. Basically everything is not so far away. It is very clean and not losing to a five-star hotel in this aspect.
The wifi connection in the bedroom was not very good and sometimes you just lost your internet. The neighborhood at late night could be very noisy. So you could hear people talking, sometimes laughing and partying loudly at mid-night or even later, thus making it challenging to fall asleep if you are sensitive to noises.
Many thanks to Filipa for making the reservation of a taxi driver to send me to the airport early in the morning. She always responds very quickly to your inquiries and messages.
