This is a wonderful flat, very spacious and at a very good price!
I stayed in this flat with two other flatmates for five months. The three of us are completely satisfied with the experience because the flat is quite big, with VERY spacious rooms and VERY comfortable and big beds. Indeed, the rooms are amazing and they have everything you may need, including small balconies! Moreover, the common areas (living room, dinning room, bathrooms and kitchen) are very spacious and cosy too.
As to the location, the flat is 20 minutes walk from the city center, which seems very reasonable considering its price in comparison with other apartments in Athens. Honestly, the relation quality-price for this flat is one the best you can find in Athens, and particularly in this area, without any doubt! There are two metro stations 7 and 12 minutes walk from the flat (Viktoria to the North and Omonia to the South, respectively), as well as a bus stop right in front of the apartment building. More buses can be taken to all parts of the city from the bus stop in front of the archeological museum, which you can reach in 6 minutes by foot!
As to the hosts, the Gpm Staff are very kind and helpful! They assisted us with EVERYTHING we needed. As soon as we arrived, I let them know about some things that needed to be fixed in the flat and in a couple of hours a technician was there to make an initial assessment. They continued helping us with any problem we were encountering during our stay, in a very kind and professional way.
Nevertheless, there is a drawback in relation to this flat. If you do not like cats or you are alergic, this may not be your place. The hall of the apartment building is full of cats (maybe belonging to any of the neighbours), and this may turn annoying at some point, specially considering the terrible smell in the hall. Sometimes, the cats would even pee and/or poo in front of our door. However, this did not diminish our satisfaction with the flat in general words, because the flat, unlike the apartment building hall, was very clean.
In conclusion, I and my flatmates are VERY SATISFIED with this apartment and would not hesitate to book it again in the future whenever we come back to Athens!
