We were staying with my husband at Vaitsa's place for 5 days and it was a great experience. The apartment is new and very clean, with good maintenance, it looks the same as in the pictures provided. It offers everything that you need for your stay!
The location is also very good - near to an underground station and in walking distance from the Acropolis. This helped us a lot, as due to the high temperatures we got to the apartment everyday to take a rest between 2.30 pm - 4.30 pm. In addition near the place there is a street with super tasty and cheap restaurants.
The only surprise that we experienced is that there was no option for free luggage drop before check-in, so we had to pay EUR 10 to leave your luggage.
To sum up, I would DEFINITELY RECOMMEND Vaitsa's place for a stay in Athens. In fact, after going back from our vacation we told all our friends about this lovely apartment that played an essential role for our good time spent in Athens.
