Initially I booked another apartment which is also a listing under tia and mike but due to last minute, unforeseen circumstance of flight cancellation and delay in travels due to bad weather, we had to forgo the apartment with no refund. Tia and mike only asked me to booked the other apartments they have.
Hence I booked another pretty apartment but the location is not close to metro (30min walk) but close to centre and attractions. If you take a cab, it is very accessible. Cabs are cheap at about 5 euro per trip around the city and 20-40 euros to the airport depending if it is during peak hours. If you do not plan to take a cab you can choose other listings that tia and mike has.
Check-in was very easy with photos and videos of how to do it. When opening the master box, you need to pull the inner button backwards to pull out the box. Your room has your name on it. The apartment is very clean and nicely decorated (very artsy). Towels, soap, moisturisers etc are all provided. Would be better if there is a hair dryer but did not find any. Hot water works well but you need to turn on the heater 20 minutes before bathing.
Pre-communication were very responsive. However as Tia and mike rented the apartment like a business and has many listings and apartments in Athens, there are many repeated messages using a standard template being sent to all their air bnb users for all their listings. I found it unnecessary and felt a bit intimidated by the long and unhelpful messages eg any help required from owners will require a payment of 50 euros. While I understand the details of the messages stem from good intentions eg reminders to keep the apartment clean as it is shared rooms, I felt that messages could be paraphrased in a positive tone and to keep it succinct, rather than warning messages with capital letters.
Overall, it was a comfortable stay with good facilities in a clean and nicely decorated apartment. I will book for their apartments again, perhaps those that are closer to the metro.
