We had a great time at Vasso. Here are the positive points : excellent location, 5 minute walk from Monasteraki metro station, we never had any issues to contact Vasso. We would also like to share the information concerning the storage. There are no drawer in the room and the bathroom is pretty small.. Since it's Europe, we were expecting that but it dosent give a lot of room to prepare yourself in the morning.
Overall I would strongly recommend this rental. Thank you Vasso
