The apartment is great, very clean and really appreciated the two bottles in the frigo and the quantity of shampoo, and shower gel found.
Also very generous quantity of towels provided.
The host (Romanos) is easy to communicate with and very fast to reply.
About the position it depends... it is very central, a lot of things to do and very well connected by metro but keep in mind that on Friday and Saturday can be noisy given the amount of bars/restaurants in the area. But I put anyway 5 stars because this is not related to the flat itself or the organization which was great.
