Me and my girlfriend will definitely be coming back here. The view from the balcony was breathtaking and blew our expectations. The hot tub added to this was just incredible. The balcony alone is well worth the money.
Inside was also beautiful. The decorations and lighting were really nice. Be prepared that it's a small space, but we didn't mind. Just enough room for 1-2 people at most. We were very comfortable.
Issues I had were that the fridge stopped working when I arrived. not a big deal, but couldn't have cold drinks during my stay. The host was responsive when I brought it to their attention, but sadly it was an issue that couldn't get fixed before I left. Also be aware that if it's windy during your stay the swinging chair on the balcony can make a lot of noise at night. It's also not the safest to sit on as the bolts are a little loose on the base. Not a big deal though. Another thing to be prepared for is we ran into a couple cockroaches. This does not mean the room wasn't clean though, if you've been to Athens before you'd know that they exist in the city. There's nothing you can really do about it, but I think it's fair to get a heads up. No other issues other than this.
The location was perfect. Right next to Plaka you get a great nightlife. There's no shortage of restaurants and cafe's close by. Extremely safe and tourist friendly area. Many attractions just a couple minutes walking. We never had to take a taxi for most sightseeing.
Overall, it's definitely worth it and you're missing out if you don't come here!
