Hi, may I know if it is possible to add one more bedding (for an adult) for a [Double Bed Private Shared Bathroom (Shared Bathroom)] or a [Standard Twin Private Shared Bathroom (Shared Bathroom)] booking? And how much will it cost?
If you're sleeping in the dorm (as I did) there is no space for adding extra beddings. I am not sure if they have private rooms. I think all their bathrooms are shared but they may have the odd private on in their private room. I think the top floors have those. If you're looking for privacy perhaps AirBnB might be a good choice for couples? I loved this Hostel & I highly recommend it to all adventurous travelers!
