When staying at the Mercure Budapest Buda Hotel, it happened that there was a hotel renovation so that it became less comfortable. Overall service is quite good, it's just that there is no drinking water every day. Bottled water is only provided once when it comes so you need to find it yourself if necessary (buy it yourself). Near the hotel there is a super market to overcome this. Last year occupying a room that has not been renovated, this year occupies renovated rooms, narrower and simpler new rooms.
