I want to thank Konstantinos. Me and my friends had a struggle finding the water heater ( our mistake because we did not read the instructions haha ) and he asked to come over and help and he was there 2 minutes after I sent him the message. Note that this was during a storm and it was very cold!
Also, his mother was a very nice lady, we loved her !
Flat was super spacious and you cannot ask for a better location which is so quiet at the same time! The flat was also vintage decorated and it provided cooking equipment, coffee, water.
Thank you for the experience and see you again for sure!!!
