I thought I’d simply make a list of pros and cons to hopefully help someone out.
Pros:
The location is quite close to the center, about 15 minute’s walk to Monastiraki, 20 minute’s walk to Syntagma. There’s also an awesome market with fresh produce about 10 minutes walk from the house, it will make you grateful for your kitchen. The renovation in the apartment looks quite nice. There is a wide array of spices (if you’re a cook, you’ll definitely appreciate this). There’s a washer (and detergent, which is a plus). The hosts are also very nice.
Cons:
The building that the apartment is in is quite old, and the breaker is weak, meaning that you have to preheat your hot water to shower, and if you have too many things turned on your power will go out. The apartment is also on a main street, so it’s quite noisy. If you have trouble sleeping this may not be the place for you. As a side note, the hosts were kind enough to leave earplugs, but I’m not someone who can wear them, so they were of no use to me. Also, the bathroom is quite small, hard for two people to use at once (if you’re a really tall person, like 6’4 you may bump your head on the ceiling—ps, the ceilings through the rest of the apartment are nice and tall).
Hope this helps! Overall, it wasn’t a bad apartment, really what you’re paying for is the location.
