This is an excellent apartment. The bed is very comfortable and bedroom is dark and quiet, so easy to get good night sleep.
It is very easy to get to all main attactions by metro, but be aware that there are a lot of pickpocketers that travel the metro.
It is very easy to walk to the waterfront and several attractions from the apartment.
It is a very nice neighborhood with a variety of shops and a nice market.
We did not meet Sophia, but communicated several times via text. She seems to be a very nice person.
