We spent 5 weeks in "Margot's House". Everything was as advertised and as expected. The communication with Lena was without problems. She was very helpful and made our stay perfect.
The house is big and ideal for a family or one couple. It is located in the 'old town' of Chania - so expect 'noisy nights' since there are few bars and restaurants near and it can get loud. That is the only drawback, I would say. Apart from that, the location is perfect. You will have a small beach just 5 minutes walk from the property. If you wish to explore other beaches or cities, the bus station is 15 minutes walk. Very near is the city bicycle station as well that we utilised often.
Lena organised a cleaning service once a week. We had access to clean beddings and towels.
There are 2 ACs - one on the first and one on the second floor. Kitchen is fully functional; as well as the washing machine. Lots of books to pick up in case you forgot to bring yours :)
Internet connection was sometimes a bit 'slow', but nothing to be worried about (we were able to work from there for 2 weeks).
Restaurants, coffee-shops, markets are all in 5 minutes walking distance.
In summary, we enjoyed our stay in Chania and Lena was a great host!
