Gabriel was extremely prompt at replying to all messages and very helpful — he shared a guide to Athens, recommendations on public transport, and even arranged for taxis to the airport on the day of our departure. He helped us switch apartments when the one we had originally booked became unavailable. He also let my brother keep his bag in the apartment for a few hours after checkout, which was very appreciated.
That said, I think this apartment is more suited for students or other young people, eg backpacking. My family just needed a spot for less than 24hrs — showers and one night of sleep before flying out of Athens — so we went with this cheaper apartment, but I think a stay any longer than that would have been difficult. There was a dead cockroach in the bathroom and a thick layer of dust on most surfaces when we arrived — Gabriel quickly arranged for cleaners to come when he realized they hadn’t been there after the last guests, but it threw off our plans for the day and even after they left the apartment was a bit grimy.
Other things to note: The apartment is on a very steep street (steeper than most roads in San Francisco) so parking proved really difficult. It’s also ~15min walk from the nearest metro so we walked into town, which was doable. It’s a quiet residential neighborhood so you’ll need to wander a bit to find stuff to do/dinner options!
