Good location, about a 15 minute walk to Acropolis and Plaka if you're a fast walker. Very easy check-in, with a lock box and on the ground floor, which is nice if you have heavy luggage.
The apartment is spacious, and good value for its size. But for the sake of accuracy, it's not actually a two bedroom place: there is one bedroom, and a big living room that has a double bed in it. The kitchen is not truly "fully-equipped" : it has a single hotplate and a plug-in oven. That's fine, because around the corner is an amazing collection of very local tavernas, cafes, bars, a delicious bakery...very vibrant and inviting especially in the evenings and feels very local and hip, not touristy.
The place is budget-friendly, and expect to get what you pay for. It could use a deep cleaning, has a hostel kind of vibe. It's darkish, rather than bright as described, well-worn, old bedding. It's totally fine as a place to crash, does the job.
Emmanouil was very nice, however and very responsive, good communicator, helpful with information, so that aspect is great.
