This was going to be a much higher rated review due to the value this room had and its location to the metro, however, on our last night, someone entered our room during the day while we were gone (with the Do Not Disturb sign on the door handle), turned off the A/C and took the remote for the A/C. A complete breach of trust and that left us with a hot night in Budapest. Too noisy on the main street to even leave the window open.
Take a hard pass on this accommodation as there are plenty of other places in Budapest that would have the positives of this place without the risk of your room being invaded.
