Hi,
It has been a few hours since I booked a Double Harmony Massage 60 min for April 7th, but I did not receive a confirmation or tickets from you. Can you please send this to me at your earliest convenience.
Thanks

Dear PK,
We have replied to your other comment, thank you.
Today me and a friend went to the szechenyi baths and her glasses dissappeared, they were right on our side along with mine and in a period of time of 2 minutes they were gone. The staff wasn’t willing to help us and we couldn’t enjoy the experience and the money we spent was lost. Stealing glasses is just ridiculous but I think the staff could have been more helpful and nice to us.
Dear Filipa,
Thank you for sharing the above and we are truly sorry about the missing glasses!
We kindly suggest checking with the Lost&Found Department in the bath, they may have found them.
Again, we are very sorry for this incidence and wish you a wonderful rest of the stay in Budapest!
