Our stay was excellent. The pictures match the apartment really well and Vivian had set the beds just as we needed. The instructions for our check-in were very clear. We arrived late because our flight was delayed, and it was already dark, but we bad no problems following the instructions. In the meantime, since we were a few hours late, Vivian reached out to try to help us. We didn't end up needing it and I didn't see the messages until later, but it was great comfort to know that she had our backs.
She sent us recommendations of places to visit that were very useful in our planning and then a lot of the times we just walked to the most touristy places, like the Acropolis, Syntagma Square, and Plaka. When we needed to take the subway, we just walked for a few minutes to get to the Omonia station and from there to all of the city including a direct metro ride to the Piraeus Port to get into the ferry to the Islands. There were several nice places to eat around and a few supermarkets close by. The coffee machine was put to very good use in the mornings with some food from one of those supermarkets just before our days of sightseeing.
In the last day, she was very flexible and helpful considering our flight departed late. I really can't recommend them enough.
